Hair is a tricky thing, you've gotta be careful if you get it cut REALLY short that it doesn't look like a butchy lesbian cut (one of the first pieces of advice i ever recieved on the matter).
pam i'm really sorry, but i have to disagree, having it really short on the side and maybe 2 lengths longer (on hair trimmers, maybe a 1 on the sides and a 3 on top) has helped me to pass more often. from the look of the picture, i had my hair similar to marcos (also really wavy) until about 4 months ago when i begged amy to buzz it all. maybe it's just me, but it seemed like i was passing a lot more often with the military style look (side burns are cut short if not completely shaved off).
until you start feeling more comfortable (and i'm sure the t will really help with that) try a shorter cut.
and to pam, amy said the same thing that she would miss my hair, but after a while she started to like it more (it's fun to pet, kind of like a seal pup) and doesn't want me to grow it out.
play around with it, remember, HAIR GROWS!
