Last night, my boyfriend and I were fooling around in my car. We did not have sex. He fingered me and ate me out. He jacked off and I helped him a little. He came on my stomach and everything was fine. We used a towel to clean up. He made a joke about checking to make sure nothing got down there, but I didn't catch that he was joking. I panicked because I thought he was serious. Without thinking, I wiped myself using the same towel. I didn't wipe immediately after him. A few minutes went by in the time he wiped and threw the towel in the front seat. He fingered me while playing with himself but he didn't get past the top of the clitoris because of my position. Could I possibly get pregnant? Tomorrow is supposed to be my last possible ovulation date. He doesn't think anything will happen. Two of my close guy friends keep trying to tell me not to panic but I can't help it. I didn't even sleep last night because I was too scared to lay down. Please give me some advice.
