Desperate!!!! Our is becoming more of a responsibilty than fun? ):?

So I've been dating my boyfriend for awhile, and we have had a lot. But it used to be for the fun. And after a situation where I felt uncomfortable, we stopped for awhile. Then we started back up again. And now we're kind of in the same situation but with him instead of me. And I've noticed that when we stopped we fought A LOT more. I mean, we were at eachother's throats. So I want to stop for the sake of him not feeling guilty, but I want to keep going because it made us closer and we love eachother. But now I feel like we're doing it just to save our relationship instead of doing it for the love. I really need help as to how I can make this better. Like other good effective two-person stress relievers, anything. Please help because I know I'm not the only who has been in the situation where is more of a resposibilty...Thank you for any help ):
