We've been dating for four months or so. In other words, it shouldn't be like this. I'm feeling really down because I have never had bad sex with significant other before.
We have no problem finishing a movie. We cuddle, but that's it. We go to bed. One of us will initiate. After like a minute or two of him being on top he'll say he's tired and lie down. I'll be on top for the same amount of time. It feels good because he has a nice tool but there's like no passion, no desire, no chemistry.
It wasn't always like this. In the beginning it was so hot and we did things spontaneously. It'd go on for half an hour to an hour (crazy, I know). Like I'm baffled as to why things got so bad. Does he just get turned on about having sex with someone new but after a couple of times it just becomes routine? I have no idea.
After another bad session I got so depressed I actually waited until he fell asleep and left. I know the answer is to communicate, but how do I do that? I tried asking what he likes. He says he likes everything we do. I so want to tell him point blank we have no chemistry but also know that there's no coming back from it. How do I resolve this?
TL;DR: Bf of 4 months and I had great sex in the beginning which quickly got boring. How do I bring this up? Should I, even?
