My boyfriend and I was just sitting on the couch watching T.V. Then we started kissing and eventually one thing led to another and we were humping each other or having dry sex, It was my first time doing it. He then told me how his sperm came out ,and I totally freaked out. He was wearing his boxers and basketball shorts while I had on some fairly short shorts and my underwear on. I got scared and ran to the bathroom to see if anything seeped through and there was a wet spot on my underwear. I'm pretty sure its mine, but it had a certain odor to it. I've read other articles about this ,but everyone had on jeans and thick pants on. I'm sure I am making a big deal about this; plus, my period is due anytime.. So i'm just really worried and need some reassurance that i'm not pregnant. Please someone answer as soon as posisible.
