you said that sperm can't get thru clothes. but lets assume he was not wearing his shorts.

let say for a moment that we were both ONLY in our underwears literally. two very thin layer of cloths. what are the probability then? are you sure that sperm would not go thru?

i guess what i am asking is what exactly do you mean by clothes? clothes=fully clothed (like with shirt, shorts, socks, the works) or clothes= partly clothed (just underwears)

thanks for the help. i am a bit paranoid.

When I say clothing, I mean underwear as well. If both of you are wearing underwear, two very thin layers of cloth, and he should ejaculate (remember there isn't sperm in pre-cum except if he just ejaculated a few minutes before and hasn't urinated), the moisture of semen could make the underwear feel moist, but then it has to go through your underwear as well. It can't do that.

Now, what it can do. IF there is enough ejaculate to get on the skin outside of the underwear, and that sometimes happens when a couple is really feeling high sexual arousal and not paying attention, then the semen on the skin may slide onto your skin up near the entrance of the vagina.

That still doesn't mean that is high risk behavior for pregnancy. It is really not very likely at all. You are far more likely to get a sexuallty transmitted disease than pregnant. You didn't ever mention if your partner has had intercourse before where he might have gotten a disease that he isn't even aware of. That is what you are more at risk for if he has had prior sexual relations.

I hope this helps and if you still need more information, I look at my questions about every two days while I'm on vacation.
