I suggest "treading lightly and very carefully". Some "straight" guys are intimidated by gays, in part because the straight guy fears it challenges his masculinity. Like you, I like the masculine male. I have yet to meet a straight guy I would come onto. That does not mean I have not met straight men I would LIKE to come onto.
I am aware there are str8 men who enjoy being anally penetrated from time to time, and they more often than not will hookup with a gay guy. I have a longtime friend who had a regular bottom mate who was married to a woman. He really liked getting his hole plugged, and his wife refused to use a dildo on him. So, voila! He found my friend and they had regular fuck dates each week.
Having studied human sexuality, homosexuality in particular, for the last 50 years (as I was "coming out"), I wonder if putting labels on sex becomes the negative? "Gay" often equates to feminine or effeminate. As both you and I know, there are thousands of very masculine gay men in our world. We just aren't as "detectable". I had a young assistant a decade ago who during one of our office chats commented about gays. He said he would feel flattered if a gay man came onto him, and this kid was not to the best of my knowledge even close to gay. It is all a matter of perspective and perception. Sorry to have rambled on so.
