Difficulty: Moderately Challenging
Step1
Remember the last time you two were intimate. If you can't remember, this could be a warning sign that your boyfriend is gay. If you don't have what it takes to get his engine running, he'll likely withdraw from you, and your sex life will become minimal or nonexistent. Be aware, though, that some gay men go the other way and overcompensate for their sexuality by wanting to have sex with their girlfriends all the time.
Step2
Pay attention to his mannerisms. If he appears to be effeminate and extra-sensitive to your feelings, it may be a sign that your boyfriend is gay.
Step3
Look at his grooming habits. If he takes longer in the bathroom than you do to get ready in the morning, that could be a warning sign. Owning lots of different beauty products and being up on the top designer shoes and handbags could mean that he's playing for the other team.
Step4
Notice if he's vocal about his distaste for gay men. While it seems counterintuitive, many men that are still in the closet become "gay-bashers" as a way of protecting their true identity. So, if your boyfriend is quick to tell everyone around him that he isn't gay, that very well may mean that he is.
