If you want to come out come out. Personally, I can understand your situation with the females even though I'm not gay. I worked at a place where I was the only male and the women were all twice my age and none of them were attractive (though that's not the point). I'm married but it didn't stop them from talking about me right in front of me and or hitting on my and stuff like that.
It was VERY uncomfortable.
In fact, it went so far as one of them talking about her sex life in front of me and me telling her I didn't care to hear about it, at which point she proceeded to offer me oral sex. I said, I'm married. She said, so.
I immediately told the supervisor. She was suspended for one week and back at it again the next week. Needless to say I didn't work there very long. But this wasn't harmless flirting. This was out and out sexual harrassment by multiple employees. It was flattering at first, but got old really quickly. The employees there were ignorant in my opinion, and it's scary that they even have a job at all, let alone the ones they had taking care of sick people.
Why not just say, "I'd appreciate it if you NOT do that anymore." If it doesn't stop, tell the supervisor you are uncomfortable with it."
Of course, if you do this it might create some ill will and then when they do find out you are gay, they'll treat you poorly.
They are going to find out eventually though, I would assume.
I guess the question is are you comfortable with telling them? I'm sure it's a very difficult thing to do, depending on the people around you and how tolerant/open minded they might be.
I live in the bible belt and have worked with a couple of gay nurses and nurse aides and they were well received for the most part by everyone.
My take is that personally I don't agree with the choice (if it really is a choice), but if it doesn't really matter as long as it has no affect on your job and it shouldn't, and though I think it's wrong, I don't know anyone who doesn't do things wrong. I am certainly not above reproach in that category either. I'm sure I do a great deal of things that many would consider wrong. We all have our own views of the world and what is and what should be. That doesn't necessarily make our views right and other's wrong.
That's why I wouldn't treat you any different from anyone else. People who are intolerant of differences based on sex/race/religion, etc. are ignorant and insecure. You can include sexuality in there but many might disagree because many believe it is a choice. I lean that way but it is for sure that no straight man knows the truth so what can one really say? Kinda like abortion. I'm generally against it except in certain cases however I am not a woman and have no idea what it would be like to have a child growing inside me therefore I don't choose to attempt to impose my views as the right view on others.
Man I'm sorry, I know you didn't want to hear all this nonsense. You just wanted advice on your question. You probably get tired of this same old stuff coming up. Anyway, good luck with your delemna and I hope it works out for the best.
Keep us updated on how it turns out.
