So today my SO and I were having sex for the first time in a week and we just started I was on top and going pretty slow just getting into it and he was like pushing my hips then he pulled me up and just as I asked if he was that close(we weren't wearing a condom we typically put it on after a little bit) he came and it like shot out faster than I've ever seen and freaking almost hit me in the face! And there was so much! But he said he hadn't finished but he won't explain to me what happened he still had a major boner but he didn't want to keep going! What am I missing here?!
