Hi wakel2000,
Hey there, hope you're doing well. I read this post and my first reaction was, uh oh, this guy sounds like hes into you.
So, age aside, i'm 27, remove this guys presence from your mind, and figure out how you really feel about this. I've been dealing with this too, having gay guys as JUST friends. I've had older gay male friends through social organizations like choruses and stuff, but i feel like if i were to hang out alone with them, that this kind of thing might come up.
So figure out what you're comfortable with, and you set your own boundaries. if you're into this guy then by all means let it happen.. but if hes gay then theres a chance that hes into younger guys. So.. just don't exempt him from the gay category.
I've thought before, oh this guy isn't attractive to me, therefore I don't have to worry about anything sexual happening... but, hes a person too and sometimes people can't help being attracted to you. I recently had to end a friendship with this 40 yo guy, because although he respected my feelings of only wanting to be friends, he would still play emotional games BASED on his deeper feelings for me.
So watch out. I would hate for you to really rely on this guy as a good friend, only to find it to be emotionally difficult for you
I hope you guys can be just friends tho. Gay friends are wonderful to have.
