The notion that men crossdress as women to attract other men is so 1950 Lots of silly and outdated stereotypes being propagated.
First of all, basically every gay guys I know is interested in men. The maleness of men is what turns them on and interests them. Even the most effeminate gay guy I know is focused on attracting other gay men, who again, are not interested in lady bits. Keep this in mind, what clothing is considered normal to wear is based on a social construct. Men wear suits and ties and women wear dresses is something that is a social normative behavior. Men in the south sea islands wear sarongs and scotsmen wear cute little kilts and no one accuses them of being gay. Sexuality and being straight or gay is a sexual orientation. Sure, you can be gay and crossdress, but there’s no direct link between sexuality and the clothes that people are wearing.
The vast majority of crossdressers are hetrosexual. The reason for crossdressing are varied across the spectrum.
