I have been with several men. It has been interesting. Both guys where gay so not really into the whole cross-dressing thing. The sex? Amazing. Loved being with a man, being controlled and dominated so to speak. And I often wonder about being with a dominate woman but those are few and far between. So to answer your questions; 1, yes 2, very yes 3, sometimes but totally worth it 4, yes there is but it is addicting really think if what you want long term 5, not really I still feel disforic often but it did answer a lot of questions for me 6, I don't know about heels and all dressed up but I would love to be.
All this said I have a loving wife that is trying to adjust and accept me for who I am and I wouldn't be willing to give that up for the world no matter how our relationship transforms in the coming months and years.
