 [ Symptoms ] can you get pregnant when semen seeps through nylon shorts onto vulva and while she is on period no penetration occuring one night she had nothing on down there while i only had nylon gym shorts on we were rubbing together near her clitoris and probably close to her vagina and i ended up ejaculating no penetration occurred some semen seeped through my shorts though but i am pretty sure i pulled her pajama pants up before a lot got out i can not remember for sure however if i pulled her pants up before or after i came she was also on the second day of her period and she had a tampon in should i be worried [ Disease ] hi i think it was more like a damp patch than semen and semen would not last long going through nylon it really loves nice and warm moist places to moves around in so you was really safe this time but what about next time when things go a little bit further never heard of condoms and has your gf never heard of the bc pill if you want to get her pregnant just carry on i do not think it will be long before she is pregnant do you really want that ok get your condoms on stand by and get your gf on the pill before things do go wrong remember safe sex is the best sex ok good luck
