<human>: Could you distill the essence of the text into 1-3 sentences?

Married 5 years. Sex is almost entirely for procreation at this point. Almost clinical because she wants to start having kids so bad. I love my wife and she is smoking hot, also I am really glad that we waited until  marriage (she was a virgin but I wasn't) but I am more sexual than her and it's really hard to bring up our sexual preferences without coming across as comparing her to my past partners (sensitive subject).  

When I do ask her about her kinks or deepest desires her responses are real Luke warm and it's stuff like, go down on me. But it seems as if she doesn't have any fantasies of her own. I know some people will say, "that's why you have to try before you buy!" But I am past that. 

Any advice on how to get her more into it? If she just once would say, "hey we should try this, or I want you to do this to me (besides go down on her because I already do that)" it would make my week. If she actually initiated a handjob without expecting anything in return I would be shocked, like who is this person?! A blow job is out of the question for now but maybe some day.

I try being as selfless as possible. Sex is always about getting her off first because "I can always get off" but it's like she never craves the D. Sexually I don't feel desired, unless it's in her fertile window and it's obvious she's just using me for my baby juice. Also, I'm not interested in using that as a bargaining chip. Don't want to play games.
<bot>: Wife seems only interested in the same few sexual positions, very task oriented on achieving her orgasm. How can we create a more equal and curious sex life?
