Not sure if its a 'problem' really but its getting to me a bit.
DH and I have a brilliant sex life, really its fab. I mean sometimes we can go a while as we're tired but its always great.
We keep everything varied and have alot of fun together.
I really enjoy going down on him but (and heres the problem) I can't make him finish 
We do it alot and I know he enjoys it, I know my technique is good and I'm not bored, I really like it, but we always either move onto sex or he 'takes' over to finish.
I know its not a massive thing but I feel kinda down about it as I'd like to be able to do for him what he does for me.
But then I can't orgasm without clitoral stimulation, which I end up contributing myself during sex most of the time. And its not an issue for me.
I'm not even sure if its an issue with him, but it is for me, I just start off thinking I'm gonna do it this time and it doesn't happen. I feel a bit of a failure in that department. I know he enjoys it but I want to bring him to climax myself.
I don't really know why I'm posting, I suppose because I can't say this to anyone in real life 
And I'm not sure I could do any more than I do??
