LGBT!! Does this make me Selfish or am I in my right to feel cheap (Read)? How do I get over this? Plz Help?

I'm with my Fiance and we decided to tie the knot things are really great between us and things are getting better, but the is well.. I feel one sided. He's 26 and has been around the block with ual experiences and he decided to settle down and commit. I'm 20 and i love this man to death. But I've only had with him and my ex girlfriend. He twiddles with my goodies and messes around and initiates . But whenever I try to initiate or if I try twiddling his junk, I get either an elbow that blocks me from touching him or he removes my hand, or changes positions so i don''t touch him. Mind you this doesn't happen ALL the time, but majority of the time he call the shots when it comes to . I like giving , but when I do so, he says it's a 'labor' to lay/sit there and take it. He use to give me oral back there, but he doesn't do it anymore. Not as much anyway. I've talked to him about things I'd like to try with him like showering with him and he shoots it down with 'It's not fun and it takes too long'. He talk about how when 'he was 20' he was as ual as I am now. Then he should understand right? I'm not your typical fag that f*cks whatever moves, but I always pictured all of those fantasies and wishes would be shared with him...But I find myself ually starved sometimes... I feel like i have absolutely NO say in our sexual activities. I know its not about the sex, but that's the only problem at this point for me. Other than that everything is great. i love him very much.
