I have frequently worked in female and gay/bi male dominated companies/departments and have gotten MANY stares. Rarely has anyone ever said or done anything directly, but I have heard comments around corners, over cubical walls and though friends that took part in the grapevine.
The only time that something happened was a few weeks after PlayGirl's only "Big Issue" was released. Some one, in a fresh inter-office envelope (no names/departments on the outside) sent me a copy of the magazine and a "XXX-Large" novelty condom, that was too large for even two end-to-end beer cans.

Luckily no one was around when i poured the contents, on my desk; which I quickly put back into the envelope, that I took home that night. I was horrified right after it happened, but after a half hour I was already laughing about it, on the inside. My friends and I had a good laugh about it that night and the demonstration of how to put on a joke condom didn't stop with those two beer cans. [Late January / early February 2000, I still have the magazine, but the natural rubber gag "condom" has since turned and been tossed.]
