<human>: BACKGROUND: In the past 2 years we've been together, it was great at first, then rocky, then I hit a downward spiral of depression because he wanted to break up with me, then we broke up, I kind of got my life back on track, we got back together, and have been somewhat rocky up until recent. Now we are doing better than ever,. 

The sex was great at first, but when our relationship hit the wall, it became sad for me, because I knew he didn't want to be with me. And I would try new stuff and all that, and ever since we got back together I'm not really interested in it. I really want to be, but I get really sad when we start having sex because all I do is remember how I felt before and how hurt I was and that turns me off (the last time I started crying, which has never happened, he didn't notice)

I really love him and have no intention of breaking things off and he loves me more than ever, I just need some advice on what to do here.. Do I talk to him about it or do I just start my own self-therapy and 'force' myself to enjoy it until I finally get comfortable again.

Give me the gist of the text in a nutshell
<bot>: Sex with BF makes me sad and I don't really enjoy it because of bad memories, but I want to again... don't know where to start
