question!

Today my boyfriend and I decided that our wait for sex is over with. We’ve been saying we were ready for awhile now but just said wait is finally over. Well we’re in bed and we were making out then we were gonna have sex. Then right before he goes to kiss me, he stops and says i can’t do it... then he got off of me and got on his back awkwardly. Now, the rest of the night has been very awkward. help????? also neither of us are virgins...
