sex issue with husband?

[ally'smom]

I've been married 5 years. The whole marriage i've been more sexual then my hubby. Lately I've been into doing more things more often. I'm 32 he is 38 so we are not young neither of us were virgins when we married. He is kind of a prude in the bedroom. Before we married I told him one sexual thing I LOVE!. It is a huge turn on for me he has only half attempted to do it once in all these years. I have high sexual needs i love doing new things/toys/positions exc. My hubby not so much is into exploring. In fact last week he hurt my feelings when we were talking sexual he said "kind of in" joking manner well your a slut. It hurt my feelings I think he is kind of uptight. Anyhow i've TOLD him what i like he won't do it or ever try. When i suggest things he makes me feel dirty or wrong for wanting more. When on the rare occasion we do something out of the usual he seems like he feels bad about it somehow.I have thought about a affair ONLY to get pleasure he is not capable of giving. I love him could never divorcee i would not cheat but, yes i've thought about it. I want suggestions or thought on how to get what i want sexually. I don't understand why he is not into the things i want him to do. He makes me feel awful for the sexual things i enjoy.
