I don't get hit on very often, but when I do, straight men do not seem to respect the fact that I am gay. I've mentioned the fact that I have a girlfriend, but I have gotten a whole host of remarks still because I am feminine.

Examples: "I realize you have a girlfriend, but don't you want another male friend to touch your genitalia?"

"We should have a threesome." (In response to me saying no) "Well, who would it be weirder for, you or your girlfriend?" ("Both of us.") "Oh come on, stop being such a tease."

"I would fuck the lesbian right out of [jesserwess's ex-girlfriend]."

What do I do about these? I'm sick of it and it really creeps me out.
