I know this is probably a really stupid question and has been asked many times and I'm not sure if this is the right community for this question, but can you get pregnant from "dry humping/dry sex?"
Here's my situation: On Monday I was making out with this guy and we started to dry hump. We were both fully clothed and I'm almost positive that he didn't ejaculate. I was wearing underwear and black leggings and I assume hew was wearing underwear and a thicker material pair of shorts (not cotton). I wouldn't be so alarmed if both (or one) of us were wearing jeans. When I went to the bathroom later I noticed some vaginal secretions on my underwear and checked to see if it went through to my leggings, which it didn't. I also checked the outside of my leggings to see if maybe he pre-ejaculated and it went through his shorts to my leggings. I didn't see any wetness/dampness or dried spots later when I checked again, although I'm not sure what pre-ejaculate looks like dried (does is look just like regular ejaculate?). And I'm assuming if there was something there it would have showed on my black leggings.
Also, because I'm the paranoid sort, I took Plan B about 21 hours afterwards. My friends say I'm overreacting, but I've been searching the internet for days and I'm just getting mixed answers. So, any help would be appreciated, Thanks.
