Long time lurker. Thought it was time to start chipping in with some questions.

My partner and I have a relatively frequent sex life 3/wk + 2bj avg. I am not unhappy with this frequency.

Issue is the enthusiasm. She can act a little flippant, a little cold, and basically act like she's not into it. For her it's a bit of a power play. She knows she has to perform for our relationship to continue, so I feel as though this is a small act of rebellion. In these cases I ignore, give it to her hard, and roll over. Still, I don't enjoy it as I want to feel desired.

I have thought about just saying 'if you act that way during sex I'll find someone who actually wants it' but as we know you can't negotiate desire and that just sounds butthurt.

So the question is, how do I approach this. I feel disrespected, and my gut says I shouldn't have to put up with this, so doing nothing is not an option.

Your insight into how you might handle this is appreciated.
