My point was simply that I'd imagine a straight dude would gravitate more to a lithe or real buff dude.
To answer your question out in the open since you went about asking it in a shitty way:
There are some straight men who look for feminine men, or crossdressers, or trans men (I've watched enough "private" amateur videos to know that straight men will fuck a guy up the ass if he's in women's clothes and shaved). There are straight men who, like a fraternity bro, will only go after other muscley jock men because their sexual curiosity leads them to only want other men who simply exude stereotypical masculinity -- i.e., a gym rat. They want to be with the men they see most often or work out with.
But most, and by most I mean about 70%, of straight men or closeted men or married men simply want discretion. You don't have to be in great shape, or feminine, to promise that. I'm experienced, and straight men like that. I couldn't tell you the number, since i stopped counting, but I've been many a straight man's first time. I know this not because they tell me so, but by their nervousness or what they want or how they want it to happen. So long as you're good at sex, and keep it discreet, then really that's all that's needed. The incredibly good looking straight bro who comes over like 2 times a week and is hard as a rock the moment we start getting frisky is proof enough of that, let alone the others.
tbh I could probably write a book about male bicuriousity in the modern age through the perspective of the receptive partner.
