Do you get turned on by dick, or just the rest of the body? If you get turned on by dick, what's it like when you see guys in toilets/changing rooms with their balls and all hanging out?

EDIT: Just saw that you didn't like going into guy's toilet's - just to clarify compared to the earlier questions, I'm thinking more mental than physical reactions and am also thinking more throughout life than just at high school. But after reading your answer to that earlier question, I have another: Would you prefer going to men's toilets or women's toilets if you had the choice?

EDIT: What do you think of girls, anyway? Just the same as straight guys do with other guys? Hmm, I wonder how that works. It's hard to compare if you can only be one or the other, I guess. D=
