My boyfriend doesn't touch me anymore?

Formerly, me and my boyfriend used to do sexual things almost whenever we could and we were always horny. We rarely had the opportunity to do it, though. He used to be really good when it comes to touching me, better than me masturbating myself.
Recently we start living together and now we can have a more active sex life and without fear that someone enters in room.
But the truth is that we don't touch each other for almost two months.

Before continuing my story, I would like to say that I don't always have orgasms.. but this is normal, I think. Sometimes when I masturbate, I just can take pleasure to a certain point and, although I can't reach an orgasm, I enjoyed and it felt good and satisfied me. (if I continue to touching myself it will spoil or not feel good / feel weird).

So what happens is that sometimes my boyfriend is touching me (he don't finger me, he just rubs my clitoris) and he's doing well, but I can't orgasm. and although I don't have had an orgasm, I already feel satisfied and I enjoyed. but I don't have the courage to tell him that "it's done" and enough, because I didn't even have an orgasm ._.
Sometimes when this happens, I do not know why but I start laughing. is stupid, I know, but I do not know why I do this. maybe I should communicate more telling him that is already enough. And I know it's my fault.

Once he asked me why I start laughing, and I said a random thing. I noticed that I hurted him because he thought I was laughing at him. But I wasn't! I'm so stupid...
This happend two months ago. we keep having hot moments and he keeps showing attraction for me, but he never touched me down there again, though. Even though I asked him to do it, he didn't showed the willingness to touch me. He turned out doing it, but it seemed that he was doing it for obligation and because I asked.

I think I ruined our sex life. I feel very sad that he don't want to touch me anymore.
Also, I don't want to talk to him about it because I think it will remember hm and do even worse.

I want to amend it. what can I do? please help
