Can’t make my boyfriend cum anymore

Mary

I’m still a virgin but my boyfriend is not. I’m not ready for penetrative sex yet but we still do other things together. I used to be able to make him cum just from a handjob but now even when I go down on him it doesn’t happen and because this is all new to me I feel like I don’t know what I’m doing. I’ve tried asking him what he wants but he will kind of get shy and say he doesn’t really know what to say. He never makes me feel bad though, and he told me he has lost a lot of his sex drive in the past couple of years (he’s 24 and we’ve been doing things together for about a year, dating for one a half) and we don’t do things more than like once a month. Has anyone else had any experiences similar to this? I want to be able to make things good for him but I don’t know how or if his sex drive just seems unusually low?
