Some people just enjoy watching drag shows just for the fun of it, but that doesn't mean they are gay. If you have your reservations, then perhaps it would be best if you talked to him about it and get your answer straight from the horse's mouth.
it does not mean he is gay. but if you really want to know ask him. drag is entertaining i have straight friends who do it because they just enjoy putting on a show I also have gay friends who do it I personally go to them because I love the diversity I see and the shows drag queens put on are most the time impressive and some hilarious
does he go alone,or with a ftiend.he knew before he started going there? if he goes alone.....well probably. but it's still not proof. if he's going with a long time friend,that you feel you know is straight then i'd tend to think he's not gay. but,it is a very odd thing for most straight guys to be doing.some( a few) of those queens are really knockouts.just keep an eye on things.
No offense but maybe he's trying to give you a hint OR two. The fact that he gets standoffish is a big clue. Why would he be that way when around the love of his life? Why should a restaurant determine how he acts around another. Is he trying to send some messages to someone or another? There is no reason for this...UNLESS...
He could be saying 'Honey, I like you and all but you could look better...' OR 'Honey, I like you and all but I also like a little something special on the side.'
I worked with a dude who always seemed to turn up at drag queen areas no matter what the city he was visiting. He said he had a girlfriend but also said he enjoyed Thai drag queen massages when on travel. He found the ' women' to be quite attractive too. Additionally, he was encouraging some work partners to read books about transsexuals and psychology. It was either he had a major fascination with transsexuals and was being upfront about his 'hobby' OR he was partly in the closet.......make your pick!
Your boyfriend could bring you to many bars without drag queens. There are probably several more Mexican restaurants in town. Don't excuse, be honest with yourself.
