My boyfriend has a long history of low libido but when we do have sex his body stills responds - he gets aroused, seems to enjoy the moment and ejaculates. My greatest fear though is that he is only having sex for my sake - that though his body responds, in his mind he is just "going through the motions". Do men with low libido still generally enjoy sex once they get going? Is it common for them to orgasm? I've discussed this with him and asked him to not do things he doesn't want to - that this hurts me more than not being interested. Still, I am never sure and it bothers be greatly. Any adivce or similar experience to share?

I am frustrated, confused and honestly, I have alot of trouble not taking this personally.
