in my experience, mansluts have no particular fashion look. its actually his look. his eyes. you'd know you're being checked out and stripped naked by his eyes alone. the intent in that look is all you need to know.
Thanks for your answers.
I thinked about physical features like big butt and things like that
It depends on what you mean and what you're looking for, I guess? I'd consider myself a slut, as I love casual sex and seek out a broad range of sexual partners, and I tend to look like a hobo.
If you're cruising for mansluts, try going to typically gay areas and see who's got either really tight clothes all over (e.g. skinny jeans, tank tops), or saggy clothing that shows a lot of skin. Part of the reason why sagging became a fashion trend is because punks in prisons let their clothes sag to indicate they were ready to get fucked, for example. A lot of slutty dudes I've met tended to be either really clean-shaven, or hairy with a good beard.
As for what a manslut should look like, if you're looking to convey your own availability, it's really up to you. Again, lots of manslut "types" tend to go deep into one end or the other, e.g. smooth vs. hairy, prim and proper versus super-loose, etc., to say nothing of accessories like leather gear, boots and the like, and you're under no obligation to push yourself into any of those niches. If your goal is to get a lot of sex, try going to cruising spots or using dating apps, and if you really want to convey you're sexually available to someone you know, the best way to go about it is usually to just tell them directly.
I think all men are sluts, they only stop hoeing temporarily when the AIDS scare gets too serious or they get the clap or something. Really just depends on the week.
I have noticed that men with tattoos, piercings, or into some kind of visible fetish tend to have HIV a lot more frequently. Whether this is a result of them being a slut, who can be certain?
