so my boyfriend and i have been going through a pretty rough spot in our relationship. he's preoccupied with school and whatnot, and has been grumpy for the past few weeks. we've strayed away from sex recently, until last night. we had just finished talking over a big fight we had a few days ago when we got to business. he was going down on me, and right as i was about to cum i burst into tears. we were both like and i couldn't stop crying for like 10 minutes. has this happened to anyone else? is it just because we've been having problems? i'm confused, help me out.
