Dry sex

I'm on the last day of my period and have a long cycle. Me and my boyfriend dry humped. We were both wearing two thin layers of clothing. By the end of it I could clearly see that my boyfriends precm had leaked through both his boxers and shorts causing a wet patch. I wasn't sure if there was a wet patch on me. But my clothed crotch came in contact with the wet patch. So, if there is a leak of precm does that mean only the fluid has got thru the material and not the sperm cells? Or can they travel through the small holes in the clothing due to being very small? Is there any proof that sperm cells can't get through clothes? Please help me :(

Hello Anonymous,

Welcome to EmpowHER. Thank you for reaching out to us with your question, which is one of the most frequently asked question on this site.

"It is effectively impossible to get pregnant by dry-humping because the conditions that would have to be met for sperm to pass through multiple layers of clothes, survive on skin, find the vaginal opening, survive in the vaginal environment and finally impregnate an egg are simply unrealistic.

The barrier of clothing that we can assume present during 'dry humping' is significant. Semen begins to die as soon as it begins to dry out and any clothes you're wearing are likely to draw water away from the sperm cells through adhesion of water to the fabric. One layer is absolutely not "like there is no clothing present at all".

Assuming some sperm cells made it through all that and onto skin, their motion isn't directed towards the vaginal opening, so a sizable fraction will be literally lost at that step. Skin is also a toxic environment on its own, so these improbable sperm have a very limited time to find their way.

That last battle buddy team of sperm has very little chance of surviving the vaginal environment. A lot of sperm need to enter the vaginal environment together to ensure that just a few survive.

As far as dry humping is concerned, there's no realistic reason to worry about pregnancy."

Above information is from the Biology Stack Exchange is a question and answer site for biology researchers, academics, and students.

Anonymous, pre ejaculate fluid itself does not contain sperm. If your partner had a prior but recent ejaculation, some sperm may remain in his urethra. But, once he urinates, any sperm is flushed out with the urine.

I do hope this answers your question.
