Fuck all that.
I know some killer gay dudes. Just because you want to fuck an ass instead of a pussy doesn't make you mentally ill (for fucks sake, being gay would be way easier that chasing women, any given night you could walk into a room and all you'd hear would be belt buckles hitting the floor). I've also met gay guys that are way better parents than straight couples I know.
Also, any gay bar you go is a crazy party (I've pretended to be a gay bear to avoid cover just laugh and watch my girlfriend pay).
Though I have met some fucking insane lesbians (I have a long story about an ex and her lesbian friend that took a liking to me and all the shit that ensued afterwards).
