my boyfriend and i were dry humping the other day,he had on khaki shorts and boxer, i had on jeans and cotton thong. he ejaculated and it soaked through and got on my jeans. it was located on my upper thigh, close to the crease of my leg. could the sperm go through this much clothing and then something get down by my vagina and get me pregnant? We dried to dry it off by standing by a fan for a few minutes and i never felt anything wet get down by my crotch. but could sweat help them swim down there or could the sperm find there way to my vagina?
