Well... since it is Pansexual Pride Day...
"My boyfriend is gay, but I'm not."
"Stop kidding. You're gay."
"No, I am not."
"Listen, if you're with a gay guy, you have to be gay!"
"I'm pansexual."
" 🤯 "
That's actually my situation. I'm pansexual, but my boyfriend is gay. To insist that I'm gay is a form of pan erasure.
