They’re not exactly massage parlors. They’re called esteticas, a combination of beauty parlor, massage parlor and brothel that are very popular in Central Mexico. If you’ve pursued your hobby in Guadalajara, you know all about them. To find them try the local newspaper, El Sol, for more ads. These will be escorts, but many give you a massage as well! In Mexico, you don’t have to pretend to want a massage if you want to hire a hooker. Prostitution is legal. But if a massage is necessary foreplay for you, it will be MUCH easier to find an escort who can pretend she’s not a whore because she massages first.  Easier to find an independent escort than a real massage parlor.
