it seems that i am the only gay guy in this forum, so i guess ill speak for all of them. if a gay guy hits on you, it is necessarily because he wants to have sex with you. half the time its just for fun. and i will admit that. its a lot of fun to flirt with straight guys, only for the fact that its "forbidden" by straight guys like yourself. and not every straight guy is uncomfortable with gay people, so i ask you not to put all straight men as the same. cause they are not, apparently some are more accepting than others. its not like he was putting his hands all over you, its only a few questions
as for personal experience, i love flirting with straight guys. and i dont do it to flatter them into sex. and i might add, straight guys do flirt back. ive flirted with every guy in my job, and more than half of them have enjoyed flirting back. and as some gay guys have a very outgoing, bubbly personality the way they talk can be seen as flirting. most gay people like to comment about everything like "you look nice" or "you smell good." so that question asking if you were a model is more than likely a compliment.
im a little offended by your post, im getting a sense that you see gay people as a lesser person.
