I guess lots of people have different definitions of what gay means, but I beg to differ on dudes who did some weird shit when they were younger and have basically straight identities throughout their lives (Sprague, Birdsong, Drasin, Rick Wayne, etc. Tinnerino may have pimped some men along with the women at one point in time but I have never heard anyone call him gay before.
I'm 99% sure you are gay, yes? This is where I think you guys and us straights are going to differ a bit. The way I look at it is there are real gays, your Morris's, Paris's, Dickerson's, etc..... These are guys that it is their true identity. They are men that love other men.
Then there are your hard gay for pay types - Kai, Duffy, etc.... I'd class them as situational gays. These are the guys that if the mood is right or the pay is right they can get into some serious explicit gay activity. You Bis, your heavy hustlers, etc.... go here.
Then you have the 3rd and 4th tier - 3rd - Your Wayne's, Namat's, Derek Anthony's, etc.... 4th - Big Sean Allan, etc.... These are guys where you might not have video of them butt fucking or sucking on camera, but they are comfortable with gay activity or in the case of BSA, comfortable for a price.
Now I'm sure some would argue that these third and 4th tier guys aren't gay, but I don't known. If you're willing to get rock hard for the enjoyment of men, if you're willing to jerk it, spread cheeks, etc.... you're gay enough or at least have the potential to be turned if the money or situation was right.
I think most straight guys here ascribe to the "build one bridge" theory of gayness

. Heck a lot of the older gays I know do too.
I will retract slightly the Tinerino bit, as I can find the reference to his pimping and other convictions, but not the G4P one. I do remember it coming up during his religious conversion though.
