I'm really freaking out right now. My girlfriend and i are both virgins and basically just had sex for the first time. I say basically because we didn't really get to the "sex" part, I was just trying to fully insert myself first, but that's as far as we got. I gradually worked about half of my penis inside. Once we got to that point I pulled out and we talked for a couple minutes to make sure she wanted to continue. The reason I am worried is after we were done talking and I tried to reinsert myself, I realized that I was going soft, and I couldn't get it to go back up. While I was inside i did not even feel like I was close to comming, but i am just really worried because I can't think of any reason why i would go soft so quickly other than if i ejaculated inside of her, which would be very bad because i wasn't wearing a condom. I may be a virgin but I have masturbated enough to know when I am about to come, and I am pretty sure it would be hard for me to not notice it, but i am still really worried that somehow I was just caught up in the heat of the moment and didnt notice. Can anyone tell me from experience if it is possible to ejaculate and not notice?
