Comprador
Gay bearish fella, forty-something, with an appreciation of mens underwear - physically and pictor*lly. In terms of the guys wearing stuff, prefer guys with a heavier build (think dadbod or bear) - especially if they are straight and/or married and are happy to stain with pi*s and c*m. I get my pleasure from having something that's been worn by a guy that I'd never experience in person. If you've got the build I like and you're a bi/gay bear/cub, that works for me too. I do enjoy trying on my purchases for size, so if you're wearing less than a 36 inch waist I'm not a good fit for you. If you wear larger that's great for me too.
Outside that preference I have a weakness for red-haired guys, regardless of build. I don't purchase physical stuff from teenagers, or from sellers not based in the UK.
As a buyer I try and treat sellers with respect, and will always leave a review. I'll not share details about how I'm enjoying my purchases in private messages to you unless you're comfortable with that.
Just reading that back - I love the scents of used underwear, but do like to have an idea about the guy wearing them.
