I'm a lesbian, but I always stop and appreciate a dude who's clothes fit him perfectly and his fashion choices are nice. I also like bony hands and feet. Manicured nails on a nice hand, and nice feet are a distraction. And when their hair and beard if they have one are nicely groomed. Not over groomed though. Cause some guys are getting done dirty by their barbers and walking around looking like their hair was painted on them cause it's so over groomed/doesn't suite their face.
I also like seeing guys whose hair looks healthy. Shiny and looks like it would be soft to the touch.
Basically, if I find any or all parts of you aesthetically pleasing, I will enjoy stealing glances at you in a non-sexual way.
