Getting Started With the Cervu System: A Step-by-Step Guide

We get it. If you’re recovering from cancer treatment, your body has been through a lot. If your treatment included pelvic radiation or hormone blockers, your vagina has been through even more. The idea of placing anything inside it probably sounds like the worst idea ever.

Using the Cervu system for the first time can feel overwhelming. You might be dealing with pain, dryness, tightness, or a history of uncomfortable pelvic exams or painful sex. It’s totally understandable to experience feelings of hesitation, anxiety, or even fear.

But here’s the good news: using the Cervu tool can actually help reduce discomfort and rebuild trust in your body. The keys are starting slow and giving your body and nervous system time to adjust.

At Cervu Health, we’ve worked with many survivors learning how to perform pelvic self-care at home. Here’s our step-by-step guide to make your first session as comfortable, safe, and supportive as possible.

Step 1: Gather Your Supplies

You’ll need:

• The Cervu tool: the handle and the smallest trainer tip

• A compatible, body-safe lubricant

• A soft towel or two

• Neutral, hypoallergenic soap

• Access to warm, running water

The full Cervu system with 4 progressive trainer tips and a rechargeable, vibrating handle.

Wash the trainer tips before every use, even if your set is brand new. Wash your hands too, using a gentle soap. Thoroughly rinse both your hands and trainers to remove any excess soap. 

When it comes to lube, we recommend a water-based lubricant without added scents. Avoid anything labeled “warming” or “tingling”—the chemicals used to create these sensations irritate the vagina. Some brands we love:

• Good Clean Love’s BioNude Ultra-Sensitive lubricant

• Ah! Yes WB (water-based) lubricant

• Slippery Stuff Personal & Clinical lubricant 

Other types of lubricant, such as oil- or silicone-based formulations, can be helpful for folks dealing with vaginal dryness. However, you should avoid using these oil- and silicone-based lubes with your Cervu trainer tips, as they can damage the silicone coating.

Bring a couple of clean towels with you to the room where you’ll do your first session. Some people like to have a towel to place under their hips during use: this helps catch any extra lubricant and makes cleanup easier.

Step 2: Set Yourself Up for Success

For your first practice session with the Cervu system, carve out 20-30 minutes just for you. You might not need this much time, but it’s best to give yourself plenty of wiggle room so you don’t feel rushed. 

Choose a private, quiet space such as your bedroom or a calm home office. Ideally, you’re somewhere you won’t be interrupted by work, chores, partners, or kids.

Set the mood to help your nervous system settle:

• Dim the lights or turn off overhead lights in favor of lower-set lamps.

• Set the room temperature to make yourself comfortable: neither too cold or too hot.

• Play soft music or light a candle if that feels grounding and soothing.

• Avoid anything overstimulating like watching TV or reading the news, which can subtly increase stress.

You’re not just preparing your body: you’re setting up a positive mental and emotional connection with this new experience.

Step 3: Get Comfortable

Lie down on a supportive, soft surface. Use pillows to prop up so you’re not straining or overstretching. Many people start on their back with knees bent and feet flat, or in a butterfly position with pillows under the thighs.

Make sure you can comfortably reach the base of your pelvis: imagine the hand position you'd use to insert a tampon or wipe after peeing. If your arms feel too short, propping up your upper back with pillows can help you reach more easily.

Your comfort is the most important thing here. You can’t relax if your legs are overstretched or your back is sore. Take your time to get comfortable.

Step 4: Calm Your Body and Mind

Before going further, take a few minutes to breathe and settle into your body. Use a guided meditation or relaxation app if that’s helpful. The goal is to let your body soften and your mind relax.

Rushing is counterproductive here. This stage is all about telling your nervous system, “This is safe. We can take our time.” 

Step 5: Begin With the Smallest Trainer

Start with Size 1, the smallest trainer tip in your Cervu set. It’s much better to begin with a tip that is smaller than one that’s too big: you can always size up later. The first session is all about creating a calm, positive first experience.

Hold the trainer in the palm of your hand to warm the tip with your body heat for a few moments. This can make it feel more natural and less startling. Once the tip is warm, attach it to the handle* of the Cervu system. 

Then, just rest the tip of the trainer on top of your pubic bone—not at the vaginal opening yet. Just notice how your body responds to the sensation of the trainer being near your pelvis. Are you tensing your glutes? Holding your breath? Clenching your jaw?

These are all common, automatic responses. Just breathe and give your body time to settle. If it helps, remind yourself, “This is safe. We can take our time.” 

*You’ll notice that the handle is rechargeable, but don’t worry if you haven’t charged the handle yet. You may not even need the vibration element for your first session.

Step 6: Explore Around the Vaginal Opening

Next, gently touch the tip of the trainer to the crease where your thigh meets your pelvis. Try both sides. One side might feel tighter or more tender than the other, and that’s completely okay. 

Notice what your muscles do—particularly your belly, your jaw, and your glutes. Are they relaxed, or did you feel them tense up? If they tightened, take a breath, add a pillow or shift positions to get more comfortable, and try again.

Then, rest the tip of the trainer directly at the vaginal opening, like you would with a tampon—but don’t insert it just yet. You’re still just getting your body used to the presence of the trainer. Again, pause and notice how you’re feeling.

Step 7: Add Lubricant

If things are feeling okay, add a generous amount of lubricant to the tip and one side of the trainer tip. You can use the tip like a paintbrush to spread some lube around the vaginal opening, too. 

When in doubt, add more lubricant than you think you need. Over your first few sessions, you’ll get a sense of how much lube is enough.

Step 8: Insert the Tip of the Trainer

When you’re ready, place the trainer back at the vaginal opening. Breathe out gently as you insert the tip of the trainer, about half an inch or less. Again, check in with your body. Did your muscles tense? Did your breath catch?

Pause here. Let your body adjust. If this is as far as you go today, that’s plenty.

If you’re still feeling okay, you can gently tilt the trainer to different angles—side to side or up and down—while noticing how your body responds. One direction may feel tighter or more sensitive. Paying attention to these differences helps you learn what your body is telling you.

From here, you can insert the trainer a little farther—perhaps one to two inches—and repeat the process: pause, breathe, and assess. There's no need to rush. Many people stay at this step for multiple sessions.

Step 9: Let It Sit (Optional)

If everything feels comfortable and you’ve inserted the trainer to a depth that feels okay, you can let it rest inside your vagina for 3–5 minutes. This allows your pelvic muscles more time to relax around the trainer. You can increase this time in future sessions as you get more comfortable. 

If your hand and arm need a rest, you can rest the handle on a rolled towel at the base of your pelvis. This will help trainer tip stay in a neutral position while you relax here.

There’s no need to advance to the next size right away, even if the smallest trainer feels easy. Let your body build trust in the process. The goal of the first few sessions isn’t even to stretch your tissues; instead, it’s about creating a sense of safety and ease.

Step 10: Wrap Up With Care

When you’re ready to remove the trainer tip, don’t rush. Gently exhale as you slide it out, and focus on letting your pelvic muscles soften. Be kind to your body during this process.

Clean your trainer tip and your hands again using your gentle soap and warm, running water. Allow the trainer to fully air dry before storing it. If you need to put it away immediately after use, dry it thoroughly with a clean towel. 

If the handle has lubricant on it at the end of the sessions, you can wipe it off with a damp towel or alcohol wipe. Avoid submerging the handle in water, as this can damage the internal motor and battery.

We also recommend going to the bathroom to urinate after each session. This helps flush out your urethra, and it’s a convenient way to clean up any remaining lubricant. You can gently clean your vulva with toilet paper or a neutral, body-safe wipe.

Finally, take a few moments to rest quietly before returning to your day. Give your body a chance to absorb the experience and reinforce the idea that this process can feel safe, doable, and even empowering.
