This has happened in class to me, but i didn't have to get up that i remember.

What i do though that i hate is get a FULL erector on the bus. Not the school bus. i take public buses. I take 4 buses every day, but it's always the second bus i take that makes me get an erection. No, i'm not horny. they just show up really big. and since i can't really adjust it so it's not as noticable, becasue the act of that would make everyone look, i have to deal with it as i get off the bus. today was HORRIBLE. it was off to the side and sticking out and even my coat wouldn't cover it. But thankfully it went away qucikly after i got off the bus and started walking the rest of the way to school. i hope no one noticed.

i don't know if it is the bus, or what, but it gets really annoying, getting one EVERYDAY. I guess it's from sitting for a half hour or so and not moving, although it doesn't bother me on the other 3 half hour trips...
