It's not the first time I've brought it up. He knows I hate the lack or foreplay and oral sex.. I'm 12 years younger than he is, and I have a sex drive that's non stop. But I've learned to control my desires better, cause I know my fiancé doesn't need sex so much. In the beginning he use to foreplay, kiss, and go down on me all the time! He said himself, "I could get off on eating a girl out" and always claimed to love it.
Than all the sudden, he stopped going down on me

(about a year ago), never foreplayes, and hates kissing. I continued to give him head alllll the time regardless. I would make sure I'm shaved, clean, and ready to go! And he still wouldn't go down.
So last night I asked him if it was cause he wasn't attracted to me, if he didn't actually enjoy oral sex, if it was this, or that, etc. he swears up and down (ha! I wish literally) that there is absolutely no underlying reason. And asked me to please stop... I've tried talking to him about it kindly, annoyed, sad, in the heat of passion, and nothing..
So I dropped it out of not knowing how to respond. He claims there is absolutely NO reason, what so ever..I'm still extremely frustrated.. I'm tired of JUST intercourse on his terms... How do I make sense of that? Any other guys that can explain his response to me? What do I do?
