Why Do I get hit on by so many gay men? I'm straight. Do I come across as gay?

I'm a 27 year old guy. I'm ok looking i guess. But I'm starting to wonder if Maybe I come across as gay? I take an effort to dress nicely. I would not consider myself metro ual. But I do make sure that my hair, and face looks ok. Usually I iron my clothes so I'm wrinkle free. I'm in decent shape. I try to wear pastel colors. I like to wear Lavender, aqua blues, even pinks , and lime green Polo, and Lacoste shirts when I'm not at work. When I work I wear a Suit and tie. I would not even be on here mentioning this, but this seems to have picked up speed. No lie, in the past 3 days, I've had 4 different gay ( I'm 90% Sure were flirting ) Men come on to me. One of the men approached me at the grocery store and would not leave me alone. Literally followed me threw the entire store. Then asked me to wait while he went to his car to get his business card. Another one approached me at a Restaurant while I was on my lunch break. I get attention from women too. But it seems more men are coming on to me? What Am I doing wrong? I don't have a problem with gays, but the way I see it, is if gay men ume I'm gay, probably women do to?
