I'm starting my first full year in our college of nursing (will be a junior... already had a quarter of nursing-specific classes and prereqs before that), and I'm out to EVERYBODY in my cohort

. During lecture one day (ie with all 80 of us present), our teacher did the diversity in religion/upgringing/race/etc (x50) thing where you go to front of the room if you are or know such and such. Of course, as we are walking back up to our spots after the "I know someone who is gay, lesbian, bisexual or transgender" where everybody goes up, she says, "I identify as lgbt." Turning midstride, I make my way back to the front, and break the ensuing moment of awkward/expectant silence with a good natured and slightly embarrased "yaaay," to which the room erupts in laughter, and I walk back to my male ROTC friends. I think there are eight guys in a cohort of about 80.
Yay for the cliché: be myself. I am open about my sexuality to peers, but usually only in passing or whatever would be normal in conversation... ie when talking about significant others, who's attractive, etc. I can't say about in the hospital, as I start clinicals this fall... though I hope to stay professional yet honest. Agreeing with Sofaraway04, if I were a gay patient, I'd feel good knowing my nurse (or whomever) was gay as well.
