How to Have Sex With an IUD: What You Really Need to Know

Understand the intersections of contraception and sex so you can enjoy both safely and with confidence.

If you’ve chosen an intrauterine device (IUD) for birth control, you’re in good company—it’s one of the most reliable and low-maintenance methods available today. But after the insertion appointment, many people naturally wonder: What does this mean for my sex life? Will my partner feel it? Could it move? And most importantly, can I still enjoy sex the way I did before?

The reassuring answer is yes—you can absolutely have great sex with an IUD. These tiny T-shaped devices are designed to sit quietly inside your uterus and prevent pregnancy without interfering with pleasure. That said, there are a few things to know that can help you and your partner feel more comfortable and confident.

First, What Exactly Is an IUD?

An intrauterine device is a small piece of flexible plastic, often shaped like the letter T, that’s inserted into the uterus by a healthcare provider. There are two main types:

• Hormonal IUDs (e.g., Mirena, Kyleena, Skyla, Liletta) release a small amount of progestin. This thickens cervical mucus, making it harder for sperm to reach an egg.

• Copper IUDs (e.g., ParaGard) contain copper, which creates an environment that’s toxic to sperm.

Depending on which option you choose, an IUD can last 3 to 12 years. The biggest perk? Once it’s in, you don’t have to think about it daily, weekly, or monthly like the pill, patch, or ring.

Will You or Your Partner Feel the IUD During Sex?

This is one of the most common worries. The IUD itself stays inside the uterus, far beyond the vaginal canal, so neither you nor your partner should feel the actual device.

What might be noticed are the IUD strings—thin threads that extend a little through the cervix into the upper vagina. They’re there so a provider can remove the device later. In the first few weeks or months after insertion, the strings can feel stiffer. Sometimes, a partner may notice them with their fingers or during penetration.

If this ever causes discomfort, it’s nothing dangerous. Most often the strings naturally soften and curl up over time. If they continue to be bothersome, a healthcare provider can trim them shorter.

Does an IUD Affect Sexual Pleasure?

For the vast majority of people, an IUD has no negative impact on sensation during sex. In fact, many report that their sex life improves because they feel less anxious about accidental pregnancy. This extra peace of mind often leads to more relaxation and enjoyment in the moment.

Some hormonal IUDs can even provide indirect benefits that enhance sexual well-being. They may reduce period cramps, lighten menstrual flow, or stop periods altogether. For some, that means fewer interruptions in intimacy and more freedom to enjoy sex comfortably.

That said, the body usually takes a little time to adjust after insertion. Mild cramping, spotting, or temporary discomfort during sex can occur in the first few months. These side effects typically fade once your body adapts.

Can Sex Move or Dislodge an IUD?

It’s extremely rare for penetrative sex to cause an IUD to shift or fall out. Your cervix acts as a natural barrier, holding the device securely in place.

Still, there are occasional cases of expulsion (the IUD partially or fully coming out). This is most likely to happen in the first few months after insertion or after childbirth. If you ever notice the strings feel much longer or shorter than before—or if you suddenly can’t feel them at all—it’s wise to check in with your healthcare provider before having sex again.

What About STI Protection?

Here’s an important caveat: while IUDs are highly effective at preventing pregnancy (over 99% effective), they do not protect against sexually transmitted infections (STIs). If STI risk is a factor in your sex life, using condoms along with your IUD is the best way to protect both your sexual health and your peace of mind.

The Bottom Line

Having an IUD shouldn’t get in the way of a satisfying, enjoyable sex life. Once your body adjusts, neither you nor your partner should notice it during intimacy—except for the relief of knowing you’re protected from pregnancy.

By understanding how the device works, what the strings might feel like, and when to check in with your doctor, you can enjoy your sex life with confidence. Pairing your IUD with safe practices like condom use ensures you’re covered on all fronts.
