People love to just give folks identities. It’s really corny. One or two people say he’s “straight”, and suddenly everyone says he’s “straight”. It’s really dopey and problematic. Unless someone presents an identity, don’t latch one onto them, and that includes “straight”. Furthermore, you don’t know what’s going on with someone’s sex life, the dimensions of their sexuality, their preferences, their fluidity, their struggles, where they are in the gender, romantic, sexual, emotional investment, commitment spectrum. All you know is what someone presents.
