After reading the RentMen ad, notice the key words in the Rentmasseur ad, . . . "Release your load . . . And find your SPOT" for the G-spot. I've heard it's a hot, erotic session but haven't as yet experienced it for myself. At least, Antonio lists a price and not "ask" to be read a menu of sorts. You get the whole package for $160 which should include finding and massaging your G-spot as well.
