It is not optional. I have to out myself as well. Any time I start getting in a serious relationship with someone I have to sit them down to have "the talk" about me being a recovering alcoholic and bipolar. It's usually a relationship killer.
Let's be honest, you have a better chance of finding love than I do. I've been single for 10 years.
Look, I don't want to fight. I just want to use humor to ease my pain. Humor is good for that. What's wrong with a joke about a trans woman?
