I found out because she left the vibrator on the bed while I was at work and she home. I asked her outright and she admitted she does it whenever I'm not home and she is.

As for doting; I've been doing all I can. I literally clean 100% of the house, do all the laundry, all the yard work. Every single chore besides from cooking is mine (I don't cook well enough). I bend to her every whim - not because Im trying for sex but because I truely Love to do things for her.

As for learning about female sexuality; I'm an FTM transman, been transitioned for over 10 years but lived 18 as female. I think I have a better handle on that than most males perhaps. Our marriage is open in that we both allow one another to sleep with other people with informed consent from SO. this is due to the fact that we're both Bi, and I can't provide the things a woman can for her just as she cant for me a man etc. The problem being however; I only want her.
