context: I live in a country which has really high homophobia rates. Most straight men from my country even believes that they will magically become gay if they have a conversation with another gay person, no cap. so I don't think that someone from my country would do these kinds of things unless they're really egotistical, narcissistic, attention seeker, validation seeker, etc.
I (22M) am gay and I have a straight friend (26M) and we are not even that close but he's been acting really weird recently. We met in an event and he got into my friend group. I know it might seem off-topic but I really find biceps and six-pack attractive, anyways, we started to chat via instagram and after a month or two, he sent a text message saying "dude, is my biceps are weak?" and sent his biceps immediately after, out of nowhere. At first, I thought that he was trying to get feedback and thought there was nothing wrong with it. He was kinda new at body building but I didn't wanted to break his courage and told him they were fine. Meanwhile he was liking most of my stories and replying them like normal friends. Few weeks later, we were at my place just drinking and chilling again like normal friends. At his 4th or 5th beer, I asked him "haven't you got beer belly yet" just because I was curious. Then, he started to act odd and stood up. he took his shirt off and said " I don't know, did I?". His belly was thinner than normal so I asked him whether he is pulling his belly in or not. He replied "I am flexing my six-pack". It sounded weird to me so I just said "okay" and the convo ended. It still doesn't make sense, is he trying to make me fall in love with him for just an ego boost or something? Is he a down-low? Or is he just being normal and I am over exaggerating it?
TL;DR: I (22M, gay) have a straight friend (26M) from a very homophobic country. We aren’t that close, but he keeps doing odd things like sending me random flex pics, taking off his shirt to show his abs, etc. Not sure if he’s just seeking validation/ego boost, secretly down-low, or if I’m simply overthinking it.
