What IUDs Really Feel Like During Sex, According to an Ob-Gyn

There's a pretty mixed consensus when it comes to intrauterine devices, better known as IUDs. Some have complained about unexpected side effects, while others take issue with the insertion process. For some, "the pain can range from sharp pain, period cramping, or like a 'gut punch,'" Megan Gray, MD, a board-certified ob-gyn with Orlando Health, previously told POPSUGAR.

The truth is, every body is different and there are pros and cons to every birth-control option, but one reason why someone might choose an IUD over an oral contraceptive is that it doesn't require you to consistently take a pill every day. For some people the potential convenience of switching to an IUD is totally worth it — but you may be wondering another question: whether or not an IUD can be felt during sex, since an IUD is placed inside the uterus through the cervix.

It's a perfectly reasonable question to ask. And to clear up the query, we spoke with an expert who answers once and for all whether or not you can actually feel an IUD during sex.

First, let's establish the basics. An IUD is a small T-shaped device that's placed inside the uterus through the cervix. You can choose between a copper IUD, which prevents pregnancy and does not release hormones, and a hormonal IUD, which prevents pregnancy by releasing estrogen. Regardless of which type of IUD you choose, the IUD will have a long set of strings attached to it, explains ob-gyn Alyssa Dweck, MD, a practicing gynecologist in Westchester County, New York. These strings are "smooth, mobile, and very thin," she tells POPSUGAR. (Think: like fishing line.) The strings are there so your doctor can easily confirm that the IUD is in the proper position, and they're also used to remove the IUD when it expires or if you choose to have it taken out, Dr. Dweck says.

When the IUD is inserted into the uterus, the strings are cut so that they come out of the cervix and extend slightly into the vaginal canal. The exact length may vary based on the individual and the medical provider performing the procedure. Typically, they can hang out of the cervix into the vaginal canal, curve around the outside of the cervix, or curl up inside the cervix canal, Dr. Dweck says.

Yes, it is possible to feel an IUD during sex, but the only part of the IUD that you or a partner should ever be able to feel are the strings, not the IUD itself. During penis-in-vagina intercourse, partners with male sex organs may feel or notice the IUD strings if they are "pointing" out of the cervix canal at a specific angle, Dr. Dweck says.

"While there is no medical danger to a male partner feeling IUD strings during sex, it may be slightly uncomfortable," she explains. "The string is a soft plastic monofilament but, at times, can give a 'poking sensation' to a male partner. This is easily remedied by trimming the strings," which can be done by a medical professional. However, she says sexual partners feeling IUD strings is "an almost nonissue" with her patients. Your doctor can help you make the call on if your IUD strings need to be trimmed. (And, for the record, your IUD strings should only ever be trimmed by a trained and certified medical professional.)

It's also possible your IUD strings may be felt during finger-in-vaginal-canal intercourse, but Dr. Dweck says the partner would really need to try in order to feel it.

If you or your partner are experiencing pain during sex that you think could be related to the IUD — and it's more than just a little poke from the strings — it could be because the IUD has moved. If this is the case, it's crucial to be mindful of your symptoms and visit your doctor to make sure your IUD is in the right position.

Dr. Dweck recommends patients check for their IUD strings every month to make sure it hasn't moved from its proper spot in the uterus. In order to do this, Planned Parenthood suggests putting your fingers into your vagina and reaching up toward the cervix, where your IUD strings should be. However, you should not tug on the string. (It's worth noting that not everyone is able to feel their IUD strings, whether it's because of the string length or your anatomy.)

If you regularly check your strings and they feel longer than usual, Dr. Dweck says this could indicate that your IUD has shifted position. If you can't feel the strings but were previously able to, there is a chance the IUD has fallen out or penetrated the uterine wall — though Dr. Dweck said this occurrence is very rare. In either circumstance, it's a good idea to visit your doctor for a checkup, especially if you're experiencing any sort of pain or you or your partner are feeling the strings more so than usual.
