Dear Dr. Betty,
I have been reading you blog for about 3 years now and it has been a great help! I am not sure who else i can ask about the situation I am finding myself in. I have met a wonderful man who pretty much from the beginning disclosed that he was into crossdressing. That in itself did not put me off one bit.
However, due to the distance and schedules, we do not have a chance to meet in person too often. We had been intimate several times and share fantasies often. As our relationship progressed, I realized that pretty much all of his fantasies are about being with other cd man and transgender women and rarely I am a part of it.
It does make me feel like he is not into me really. Should I be concerned?
Yes, absolutely be concerned. You are not into cross dressing and you are a cis women. While he sounds like a cool guy and you can enjoy sharing all kinds of fantasies with him, he sounds more like a "fuck buddy" rather than a someone you might want to embrace as a serious lover.
As long as this affair is based on mutual pleasures enjoy it. Just don't start projecting this as a possible future for either one of you. I'd see him as one of my girlfriends with her very own flesh dildo. That could be quite kinky and fun.
