I found an article on the web site self help magazine called The Real Truth about Crossdressing
http://www.selfhelpmagazine.com/article/node/1218
“More than likely not. As Dr. William Stayton, Head of the University of Pennsylvania’s Department of Human Sexuality and himself a therapist for crossdressers, reported “People associate crossdressing with effeminacy and being gay and the fact is most of them are not gay. They are very definitely heterosexual. “In fact one of the most difficult areas for crossdressers was how to deal with the women with whom they wanted to be involved.”
When I think of men dressed as women, I think of drag queens, which is often an act that is associated with gay clubs
