Whether you’re worried, curious, or just tired of misinformation, here are the answers you’ve been searching for.

If you’ve ever typed one of these at 1am, you’re in good company. Below, Kirsty breaks down the most common sex myths and medical FAQs she hears from patients every day.

Can I get pregnant if we practice withdrawal?

Short answer: Yes.

“The withdrawal method isn’t a reliable form of contraception,” says Kirsty. “Pre-ejaculate fluid can contain sperm, which means even if your partner pulls out before climax, there’s still a chance of pregnancy. If you’re not trying to conceive, use a consistent contraceptive method like condoms, the pill, or another long-acting option.”

Can I get an STI if we practice withdrawal?

Also yes.

“Withdrawal offers no protection against sexually transmitted infections,” explains Kirsty. “STIs can spread through skin contact, bodily fluids, or oral sex - not just ejaculation.”

Condoms and dental dams are still the sexiest tools for safer pleasure.

I can’t get an STI if we don’t have penetrative sex / we’re a same-sex couple.

“STIs don’t only spread through penetrative sex,” says Kirsty. “They can be passed through oral sex, close genital contact, or sharing sex toys. This applies to everyone, regardless of gender or orientation.”

Clean toys, use condoms, and communicate; that’s real protection.

How do I stop sex causing an STI?

“Always use barrier protection,” advises Kirsty. “Condoms reduce your risk dramatically. Urinating after sex can help prevent UTIs, but it won’t protect against STIs like chlamydia or gonorrhoea.”

Regular STI testing isn’t something to be embarrassed about, it’s just part of caring for your sexual health, especially if you have an active sex life.

Is bleeding after sex normal?

“Occasional light bleeding after sex can happen, but it’s not something to ignore,” says Kirsty. “It might be due to friction, dryness, infection, or hormonal changes. If you notice it, get checked by your GP or gynaecologist. The vast majority of causes can be easily treated”

If you’re bleeding, don’t panic; just don’t ignore it. Lube helps, too

Can sex trigger or bring on your period?

“Sex can bring on your period if it’s already due,” explains Kirsty. “Orgasms release hormones that make the uterus contract, which can start light bleeding.”

Your body’s doing its thing, sometimes, a good orgasm just speeds it up.

Can sex cause thrush?

“Thrush isn’t an STI, but sex can make you more prone to it,” says Kirsty. “Friction, semen, or changes in vaginal pH can disrupt your natural balance.”

If you get thrush regularly after sex, try switching to a gentle, pH-balanced lube (and maybe a partner who appreciates foreplay).

Can sex cause miscarriage?

“In a healthy pregnancy, sex won’t cause miscarriage,” Kirsty reassures. “The cervix and amniotic sac protect the baby. But if your doctor’s advised against sex due to complications, follow their guidance.”

A healthy pregnancy can handle intimacy,  if it feels good and comfortable for you, it’s safe.

Can sex delay your period?

“Sex itself doesn’t delay your period,” says Kirsty. “But stress, hormones, or anxiety about pregnancy can affect your cycle.”

Basically, worrying about being pregnant can ironically make your period late. Bodies are funny like that.

Can sex help with period cramps?

Yes - and we’re fully here for this one.

“Orgasms release oxytocin and endorphins which are natural painkillers that relax the uterus and ease cramps,” says Kirsty.

So next time your cramps hit, consider it doctor’s orders.

Can sex cause a UTI?

“Yes, bacteria can be pushed into the urethra during sex, especially in people with vaginas,” says Kirsty. “To lower your risk, pee after sex, stay hydrated, and avoid perfumed washes.”

Peeing after sex = necessary UTI deterrent.

Can sex induce labour?

“Sex can sometimes help bring on labour if you’re already near your due date,” says Kirsty. “Semen contains prostaglandins that help soften the cervix, and orgasms can trigger contractions, but only if your body’s ready.”

So yes, it’s a thing, but not a magic switch.

To finalise, Dr Hamilton added “ It’s so important to take responsibility and accountability for your sexual health to fully enjoy an active and fulfilling sex life. Going for sexual health screens aids earlier diagnosis and reduces the likelihood of transmitting an unknown infection.”

Ohmy!Gasm founder Lizzie Lew adds “No question about sex is ever too weird, awkward, or “too much.” Curiosity is healthy. The more we understand our bodies, the more empowered and connected our sex lives become.
