I think you’re the one with little idea of those people. You are describing transvestites. What has that to do with homosexuals? I think you may be a little confused.My neighbour was telling me that a builder used to keep the house opposite, and spend his weekends there as a woman.
The landlady of my local told me that one of her previous business ventures was to make up seemingly straight blokes as women.
You have little idea what really goes on in most people's lives, so to make crass statements about "proportion" this and "over represented" that is just prejudiced guessing.
