I was making out with my boyfriend pretty intensely but we both had our clothes on. He had on shorts (and underwear i am assuming) and i was wearing my underwear and shirt. I had my legs openned and wrapped around his body and legs at different times, and our genitals were rubbing eachother. i don't know if he come or not, so now i am worried on whether sperm (if any) got into me. i was also on my 3rd or 4th day into my period so i was wearing a pad although my underwear were loose.

Does sperm go through your underwear? can it impregnant someone? when someone cum or pre-cum, is it obvious? will you know?

some websites says, yes sperm can travel thru underwear and impregnate someone, while others say no. what is the real deal?

please help, much thanks

signed concerned and worried

ps. i am scared of making out now.

I am very sorry that other web sites tell you that you can get pregnant through clothes. I don't know what their motivation is for saying that because I can show you all the literature and research that there is no way pregnancy occurs from precum, or cum inside clothing.

I will repeat. Sperm is actually very fragile. It dies very quickly, and does not have very good motility even though it has a tail. It needs semen, and then inside the woman's body it needs the moisture inside her cervix and uterus to help propel it to the Fallopian tube where it meets the egg.

You mentioned that you were in the 3rd or 4th day of your period. You also are not likely to have an egg present at that time as the next cycle of producing an egg is just beginning. It would be too early in the cyle for the egg to be ovulated and in the tube. Keep in mind that it is possible for an egg to be there, but not at all likely.

It is not at all likely that sperm would be able to get to it. Sperm does NOT go through clothing, even if the clothing gets wet with the semen that is protecting it.

As I said earlier, precum doesn't even have sperm in it most of the time. The exception is if a male just ejaculated. Then the next arousal and its precum could pick up sperm left in his urethra (tube inside of penis)and bring it along. But it isn't much sperm, and I am hoping that all the web sites tell you that each ejaculation in a male has millions of sperm in it.

The reason there needs to be millions is because sperm is so fragile, and dies so easily that it takes millions to even create the possibility of a pregnancy.

I know you are worried, and I hope this helps ease your worry. I am sorry that you are finding places where there is inaccurate information. I don't know how to help you believe that those of us on this web site are specialists in this area and study sexuality. We are not trying to discourage you from engaging in sexual pleasuring with someone.

I think maybe the other sites don't want you to "fool around" because it is sinful or they are afraid that you can't stop yourself from having intercourse. We at this site know that sexual playing is good for you, is healthy and that there are so many pleasurable things you can do that don't cause pregnancy that accurate information is what you need.

Please feel free to ask more questions if you have them.

I will be back on line in a couple more days.
