Update:
Ended up finding another hot Colombian masseur on Grindr and had a really good deep tissue massage on a bed for 1.5k. Spoke little english but was really sweet and intense. No sex beyond release, but if I lived here I'd end up seeing him regularly.
Mileroticos is handy and I found some good ads. Will try to use it more during future visits.
There are so many twinks on Grindr, but so few of these bottoms have an ass, much less a big one *wails in top*
I've noticed that most of the guys I'm interested in when I visit Mexico City are Colombians and Venezuelans. Will have to plan a trip to Colombia to see if I like the guys there more.
I have a few days left. Will try to find a cute local to go bar hopping with or fuck in Sodome, because I refuse to go to either alone.
