Apparently according to research, Crossdressers are no different than the male population in general.

"current research shows that male crossdressers (who identify themselves as male) consider themselves to be heterosexual (attracted to females) in about 90% of the cases (depends on the sample), and 10% self-label themselves as bisexual/bi-curious/homosexual/asexual. Such percentages are consistent with those who identify themselves as male (whether they are crossdressers or not). In other words, sexual orientation in male crossdressers follows the same general distribution as in male non-crossdressers."

For those so inclined, here is a copy of the research study. The blogger did a pretty good job of summarizing.
