Why? What difference does it make as long as he’s doing his job well?
I’ve only ever had a real problem with one lesbian woman I worked with. That was only because she was the biggest slacker ever and she and her wife did their best to get out of work when they could. They had it made and milked it for what it was worth. That alone wasn’t the issue though. The issue was she actually had the nerve to say to me once, “If they try to change anything I’ll just say they’re discriminating against me because I’m gay”. WTH?!!?! That had nothing to do with anything. Her laziness and willingness to play the “gay card” to keep it that way was everything.
Most people could not care less if someone is gay. Hell, talk about your spouse if you want to, I don’t care. I don’t want to hear about any visits to the glory hole or your dating conquests though. But then, I don’t want to hear straight people talking about their one night stands or visits to hookers either.
Keep your dirty laundry/habits to yourself and everyone is happy.
