Khloé Kardashian admits she's not had sex for 3 years: this is what happens to your vagina when you go without

"That is a complete fallacy," says Dr. Zanotti. "The hymen is a vaginal remnant that’s there from development. It’s something that’s broken through when a woman [first] has intercourse or maybe uses a tampon. That tissue does not regrow. It cannot close up."

Women who are late into menopause may experience a slight shrinking of the vaginal opening, Dr. Zanotti says. "But there’s no regrowth of a hymen at any point in anyone’s life."

Just as many people mistakenly believe that women regrow their hymens after long periods of abstinence, there are also some claims floating around that abstinent women's vaginas 'dry up.' But Adeeti Gupta, an OB/GYN and founder of Walk In GYN Care in New York City, says this is another myth. "Please do not think that ‘everything is going to dry up down there’ because of no activity," she says.

One possible exception to this rule? As noted above, postmenopausal women are more likely to experience vaginal dryness. That’s thanks to reduced oestrogen levels, not abstinence.

Just as initiating a new sexual relationship might heighten your libido, Dr. Gupta says it may also increase arousal and "make the experience more sensual." Whether you’re sexually active or sexually abstinent, Dr. Zanotti says that arousal is always highly variable. "Everyone has a different amount of time to reach that climax," she says.

"It’s so individualised, not within just the woman but also with that person they’re gonna be with." For this reason, Dr. Zanotti says it’s important for women to allow their arousal to manifest however it does during each sexual encounter. "I think [women should] feel comfortable with it and not feel guilty about it," she says.

If you decide to stop using hormonal birth control on account of being sexually inactive, then this may lead to some changes. "When you go off whatever hormones you were on and you’re still of reproductive age, your ovaries are gonna kick in," Dr. Zanotti says. In addition to changing up your menstruation, this might also mean that you experience more natural lubrication and/or heightened libido.

Dr. Gupta says that abstaining from sex after having been sexually active is unlikely to have any impact on your libido. You’ll still feel sexual desire just as you did when you had a sexual partner.

However, Dr. Gupta does point out that your expectations around sex might change in ways that can make sex more or less enjoyable when you become sexually active again. "Sometimes, having sex after a long period of abstinence may feel a little different in terms of, either quite exciting or a little uncomfortable from the stretching," she says.

Because most women experience a slight tightening of the vagina after a prolonged period of abstinence, Dr. Zanotti says that "the first few times you have intercourse after an absence, it’s going to be a little bit uncomfortable." But for premenopausal women, this should be a temporary sensation. "Again, the elasticity comes back," Dr. Zanotti says.

Postmenopausal women, on the other hand, may find that it takes a little more effort (in the form of lubrication and stimulation) to achieve comfortable sex.

Even though your sex drive is unlikely to change while you’re abstaining from sex, you may notice an uptick in your libido if you become sexually active again.

"Having a new partner is exciting enough that it stimulates your libido," Dr. Zanotti says. "A lot of couples who have been together for a long time can get into a rut. When you have been abstinent for a little while and you have the excitement of a new partner, that can [increase libido again]."
