I just want to finish

Paige
So my boyfriend (who's the only guy I've been with) has sort of been rushing sex lately. Not like he wants to get it over with or anything. I have to be super focused and into it to finish and it can take a while (I like to be teased) and he knows that but lately he starts off paying attention and trying to get me there and teasing and being slow but he gets too excited haha and jumps right into it way too fast and finishes before I can even get close or he asks for a bj and after he finishes, he never finishes me too. He's not a bad guy or selfish or anything, we've been dating for four years and he's my best friend he just gets too excited but I have told him I need time and I don't want to be rushed and that it makes me upset how much more often he gets to finish than I do but he just always loses focus when the time comes and once he's done I'm too frustrated to get into it again even if he wanted to. How can I keep him on track without being too bossy and ruining the mood?
