My wife and our sex life

My wife doesn't place importance in our sex life. It pretty much comes dead last in her list of things to do in any given day. She says it's not a lack of desire (swears up and down that there is plenty of desire.) just a lack of time.
She has a tendency to be uncomfortable about her sexual desire. She is even so used to controlling that she can flip from edge of orgasm to her drive being totally non-exsistant like flipping a switch.

I on the other hand am a nypho, literally not just I'm male and want to have sex alot. I know the differance. Also my body produces sperm at a sometimes alarming rate. I try to be understanding and shrug it off, I try to never force the issue if I can help it and she's always apologetic when our lack of intimacy comes up. I even have been trying for just a little fore-play as I'm mostly addicted to the feeling of intimacy and joy of the physical pleasure with her.

Lately though it's been pretty bad, I'm getting blue balls fairly regularly. (I had them 11 times a few weeks ago.) And I just had a messy wet dream the other night. Something that never even happened when I was a teenager. Worse of all I'm getting more and more short temperd and snapish. I'm resenting her priorities and starting to resent her when not in her presence.

I love her completely and having never found anyone so perfect in everyway to me (except in the sexual arena), I even love her habits that annoy me, missing them when she has an irregular work schedule. I don't even enjoy porn though I've been trying to take of the problem myself I have trouble finishing and often just end up with blue balls.

I'd appreciatte any feedback or advice you can provide, thank you.
