Can sperm travel through clothing and result in pregnancy?

Can pregnancy occur from dry sex? If a guy and a girl were to be "grinding" on each other's private parts (imitating sexual motions while fully clothed with the girl straddling the guy) while the guy was wearing cotton briefs and jeans, but the jeans may have been pulled down, and the girl was wearing cotton leggings and cotton panties. Is it possible for any sperm to get through these 3-4 layers of clothing and fertilize an egg? Also, how can the girl know for a 100% fact that she is not pregnant before a missed period. (if at all possible) If it matters, I am a 16 year old female and over weight (200lbs and 5'4"), which I heard may make the girl less fertile and my partner is 17 and a healthy weight. Also, the girl was on top, so does that make pregnancy less likely? I'm very confused.. Thank you very much!

  • It is possible for a female to become pregnant without vaginal penetration, if a male ejaculates on the external genitalia. Sperm would need to travel all the way to the egg to fertilize it and the farther away they begin their travel and the more obstacles that are in the way, the lower the chances are for a pregnancy to result. The odds under the circumstances you describe are infinitesimally small, but not zero.

    "How can the girl know for a 100% fact that she is not pregnant before a missed period?" The only way to know for sure is to not engage in sexual behaviors. Home pregnancy tests are not considered accurate until at least one week after a missed period.

  • I'm not sure what biology lessons you got, but whoever told you semen was some kind of ultra-durable acidic substance was just joshing you.

    • Even if it's just 3 cotton layers? Cotton is pretty loosely knit I think, so why couldn't sperm get through?

    • @Asker Trust me, sperm cells aren't these intelligent commandos that are able to jump through your vagina, it's fine.

  • I think it's possible. My one teacher told me that she knew of a woman who was morbidly obese, her husband came inside of her thighs and not her vagina, and she got pregnant. He didn't even break her hymen. So anything is possible.

  • Not possible to go through so many layers of clothes...

    • If it got through, you'd notice, all your clothes and your body would be wet. Take the pill of the next day if you think this might have happened and be more careful from now on.

    • Speed needs bodily fluid to transport itself. They don't crawl through dry space like fleas. They swim.

    • Sperm*

  • No that is just silly

    • Girl go and get educated because your lack of knowledge on something so important is quite ridiculous

  • Sperm dies if not matchin an environment suited for itself (vagina)... it can lives a few seconds in hot water... it won't pass any surface and even when it enters in contact with the air, it dies. Dont worry :)

  • They teach you that it can. But if you research or read up on this, the chances or probability of that happening are very miniscule. still always a safe bet to use protection anyway.

  • that´s very unlikely but i´d still try to be sure about it, if i was you.
