How to have guy's hair:

This is the most important place to start. Go for a very conservative, short-back-n'-sides cut, but avoid getting an all-over crewcut or a way-out "punk" style as these are often sported by the butch lesbians who you are trying to distinguish yourself from. All-over crewcuts are also problematic because they emphasize the shape and size of one's skull and are therefore feminizing (look at Sinead O' Connor) - you've got to leave something on top.

Go to a barber's if you already feel comfortable trying one - if you don't, find a gay or gay-friendly hair stylist who's willing to help you look as masculine as possible. A lot of guys keep going to the person who cut their hair "before" - don't, especially if they perceived you as a lesbian. Even if you're not passing yet, get a new hairdresser or barber who'll help you to look male, not shock the patriarchy.

Part your hair neatly to one side and then comb the top back or to the side. As anyone can tell you, bangs are feminizing - women and kids tend to have them, but men don't. Use gel or mousse if your hair won't stay in place.

Sideburns: You know those Liza Minelli-esque "points" which grow just in front of the ears of women with short hair? Men don't have them, so cut them off straight across with a good pair of scissors. Then use a razor to shape your sideburns - start from the upper point where your ear meets your head and then go straight down.

Fake Stubble/Facial Hair: Although really convincing fake facial hair from a theater or costume supplier might help you pass, it can be problematic. It's very difficult to explain where that full mustache suddenly sprouted from and even more difficult to remember who's seen you wearing it and who hasn't.
