Hes gay

If you're a woman, you may have noticed things about your boyfriend that lead you to believe he's gay or interested in men. Sexuality is highly complex and sensitive, and there are a lot of inaccurate stereotypes out there that don't truly reflect a person's sexual orientation.
In the case of a man pretending to be straight, he may actively avoid forming friendships with gay individuals or participating in LGBTQI+ events to maintain the impression of heterosexuality.
