### Human:\ncan sperm go through clothes? . i was on top of my bf and i were dry humping but he ejaculated. he was wearing boxers basketball shorts and i was in underwear (a thong). some of the semen got on my thong from seeping through his 2 layers so my first question would be: can sperm go through his clothes and make me pregnant? if not then you probably don't have to worry about my second question. my second question is: if a little semen after going through his 2 layers got on the outside of my vagina will i get pregnant?\n\n### Assistant: sperm can only live for 30 seconds so how long did it take for your boyfriends sperm to get on your thong
