While a guy with a girlfriend at home and a dick in his mouth is going to be perceived to be at least bisexual by most comers, there are guys who aren't into men-not at all-but who love sucking dick. Or he could be one of those non-gay/non-bi guys who loves to suck the occasional dick. Or he could be secretly be a whole lotta gay but sucking dicks in glory holes is all the gay he'll allow himself. But sure, GLORY, this may be a fetishistic desire on your boyfriend's part or he could be the tiniest bit bisexual and this is how your boyfriend expresses his tiny bit of bisexuality and only his unresolved homophobia/biphobia prevents him from conceiving of himself as bisexual. Some people think kink is a sexual orientation-kinks are certainly hard wired and not chosen-but, even if they're not, drawing a neat line between a person's kink (or kinks) and their sexual orientation isn't always easy. He gave me a treatable STI already, but he says it was from a previous female partner. I'm OK with him making his own decisions about his health, but I also want to protect myself. He says he gets tested after he goes but I'm not sure how frequently he does this.
So, a few questions: Should I support my BF around exploring his sexuality? Does he even need to explore this? Do you think this is a kink or a part of his sexual orientation or both? And how can I personally protect myself from STIs? He says that they don't use condoms in glory holes. I wouldn't have any problems with this-I dated women for ten years prior to him-but he emphatically swears he's straight and often points out that he doesn't like gay porn, he doesn't like to see gay men being affectionate, etc. However, the amount that he jokes about being gay, giving blowjobs, etc., makes me think he might be gay or bisexual and is coming to terms with his sexuality.
Then out of the blue this week he said that he had lied and actually likes to go to glory holes occasionally-but only to give blowjobs, never to get them. I asked him if he had ever been to one, and he said no. My boyfriend really likes glory hole porn.
