Plenty of guys act a lil “gay” for the sake of attention or persona or to make people uncomfortable or to be “subversive”. A lot of guys in the queer spectrum act more “gay” than they are on social media for money and to build a following. Plenty of ”straight” guys on social media also bait. In general, traditional, full, life-long heterosexuality isn’t as dominant among males as people think. Some dudes do put little clues and make lil comments in order to “test the waters” or to not feel like they’re closeted. A lot of people don’t want to be legit out because of phobias, internalized phobias, fluidity, hyper-sexuality, contradictions, paraphiliacs.
The gender, sexual, affection, romantic, emotion, commitment spectrum is wide and varied. It’s impossible to say what is going on with a lot of these random guys, especially on social media. And it’s honestly not worth racking your brain over.
