He is very lucky you are willing to talk to him about his interests. My wife was totally the opposite. When she found it she closed the door on any conversation about my dressing.
You are open minded enough to come here and share your thoughts. Why not invite him to join you on the site and read the posts and look at the pictures together.
I enjoy looking at all of the other members of this site. It amazes me how fabulous some of the men look as woman, and it is a bit of a turn-on. Not because I am gay, but because I wish I could look that good. I wish I could get my wife to join me and discover that different is not bad.
Let me know what happens, I think you will both enjoy it.
