Are my straight friends ashamed of me because I’m gay?

I’m a gay men, I have many straight men as friends, in fact my closest friend right now is a straight guy, and I am by his words the only person who he trusts and could talk deep to and would listen to him.

But that’s the thing, I realized the fact that all my friendships with straight men, I’m less of a bro who hangs out and have fun or chill drinking beers and playing games together, in all my friendships, I was the one who listen and the one who they vent to who would comfort them and offer them support. We do hit the gym together though. But they wont bring me or introduce me to their guys group ever, but they would invite me over deep coffee talk where they talk and vent things inside them out to me for hour just me and him.

I feel less of a friend, of a bro, more of a confidant, emotional support people. I dont think I mind it though. I want to care for people around me, being needed makes me feel good, and my will to live is also that I have to be strong for people

But I wouldnt lie and said don’t feel sensitive in insecure around being gay, are they ashamed of me being gay so they dont show me to their friends? I dont need them to. I wouldnt want to even if they want to, because I’m close to them and want to be around them support them, but not whomever that is that I dont know, but still…
