I have a question: what's happening with straight woman and lesbians?. Let me explain, in my workplace I am the only lesbian (that I know of, there should be someone else in the closet) and suddenly woman (married ones included) are all over me. I don't mean everybody but enough to get me scared.
I am always very careful of how I treat women because I don't want any misunderstanding, but it's the other way around. It's not in my mind because some of them have made very obvious moves or have spoken about having a fling. Is it very common for them to have lesbian fantasies or something like that because I don't understand. If this has happen to any of you please share. Straight girls are welcome to give an opinion!

). Most of them probably think it's "safe" to flirt with you because 1. their husband isn't gonna be upset, and 2. you know they are just flirting (even if you don't know that for sure) so won't take them too seriously. There might be one person at the office willing to go further, but with all the flirting it may be immpossible for you to ever know which one it is. Have fun with it....
. Thanks to the straight girls for trying to explain me, it's been helpful and if I may say you would have fun here "on the other side". 
I would probably just ignore it if you can, and file a complaint with HR if someone is getting out of hand. Good luck!
