Now, what do you think would happen if the heterosexual men and women all bunked and showered together? Been there. Nothing happened. You seem to forget that a person can be a soldier first and a homosexual/woman somewhere further down the line of importance. You've got priorities screwed up. When I was in the Army I wasn't a heterosexual first and a soldier second. I was a soldier, period.
So you are saying men and women showering together and bunking together would be A-OK with you? No distractions from task? No unit problems? That's crazy. You want equality some places and not others. No one, whether "something happens" or not, should have to share facilities with the "opposite" sex or its equivalent.
If you like showering with gay guys do it on your own time.
