Subject: In a relationship but I don't like sex

Hello, I'm female and I've been in a relationship with a guy for 6 months. Each time I've tried to have sex, I've found it painful, a hassle and just wanted it to be over. I don't really get turned on. 

I don't think I'm not attracted to him because I can kiss him and cuddle etc., but I find it kind of irritating at times. If I'm not attracted to someone, I'm disgusted by holding hands with them, let alone doing anything else, so I would say I am attracted. 

It's becoming a problem because he has a high sex drive, so he ends up masturbating and asking me to help him which I'm alright with doing, but I just want it to be over and done with so I can get on with other things. There's got to be more to relationships than this. 

I do masturbate, but I wait until I'm alone to do it, and I don't think about him, or myself, when I do it. 

Any advice?

Why don't we need to fuck if it was girl I'd do her
