i am, as many others, in the same situation as you. my wife isn't really interessted in kinky stuff; we tried several times, but i can feel she is really not into this.

This leads to three options:
a) give up and try to neclect your desires
b) fullfil your kinky desires with a pro
c) find another partner.

As i do love my wife, c) isn't an option for me. And as you know how really difficult it is to find a sexually dominant female...

As after a session i do feel so much better and relaxt for weeks, it is just something i can't deny forever. So, for me, i chose b).

And: with a pro, there is no question: does/can she still respect me as a partner. A pro just doesn‘t care. As long as i am a decent bloke and help her pay her bills, she 'likes' me.
And if you find a really good one you keep seeing for years, it can become close to a friendship 'light'.
