Is it normal to be aroused by gay men who want me? (i'm straight)

It's akin to how a lot of guys will still sleep with women they don't find attractive. Ninety percent of the arousal is rooted in the desire the woman has for them, and in the nature of sexual contact itself. I don't find men physically attractive, but somehow if a gay or bisexual man shows a strong sexual desire for me, I become aroused and interested in him. I want to let him have me. As with women I don't necessarily find attractive, at the height of arousal I can even reciprocate to make it "fair", and I get "some" enjoyment from pleasuring them, but not nearly as much enjoyment as I get from them pleasuring me.

I usually avoid acting on these kinds of urges because it's not fair to the other person to lead them on. I usually only give in when I'm inebriated. I'm fairly attractive, so I get hit on quite a lot, whether subtly or not. I think it's really cute when someone out of my league or someone I'm not interested in is fascinated by me sexually. I don't feel the disgust and outrage/audacity some other attractive people seem to feel in these situations. I like to tease them and flirt with them.

I know how narcissistic this sounds, like I'm obsessed with validation, but until the sexual aspect comes in, I'm not like this at all. I'm usually rather humble and modest, and give out many more compliments than I receive. I don't think I'm "special" and I sincerely enjoy doing things for others, so what's with this weird thing? I told a friend, and he just thought I was either being "generous" with my body, or that I had repressed homosexuality buried in me, but I'm just not a repressive guy. I know myself. I think it would be interesting to be bisexual, but I'm just not, even attractive men don't do it for me, but I have no problem with them looking at ME that way. How common is this?
