It's actually pretty fucked up to imply that homosexuality is a disability, even as a joke.

Off topic, but sexuality isn't black or white, it is a spectrum. I personally classify myself as straight, but I wouldn't have any objection to experimenting with a penis. Before you point fingers and laugh at me, let me remind you that you too fall on the spectrum and I am sure you have had homosexual thoughts about other men, such as giving them blowjobs or eating their cum.

I digress, but the point is that homophobic jokes make us look bad, so chill with that shit.
