A lot of guys are comfortable with really old Asian women, and peg them often 20yrs younger than they are. Lol. Having grown up with a lot of Asians.. It's obvious to me when someone is 55+ and annoying af when someone says they're early 30s lol.
Best suggestions is to watch for posters who like your style and thru trial and error you'll arrive at some sense.
Or you just pay 220 at the proper agencies.. And you're not getting grandmas. You can shower, the place isn't a dump, and it's a easier experience to book.
So we torture ourselves to crap for 120/140hh vs 220hh . (I am one of these torturing myself as I like to imagine I'll find a gem. Lol)
