My heart skipped a beat when I saw the portable massage table symbol. Shows where my heads are at. Then I realized it is an 'occupation' icon. Then my heart skipped a beat when I fantasized it signifies a briefcase containing various essential oils, toys, rubbers, lube, vid equipment, various and sundry paraphernalia.
On Grindr in Rio (sorry to deviate from Tinder topic) it is amusing to see some profiles specify "not a GP". I guess a lot of guys get hit on with offers. I must say my own approach there this past winter "me generous, you good-looking gym guy with training costs" resulted in minimal yield. I got some responses from young slender men I would not pay for or have sex with for free. I gave compliments to ones I liked so they might see my profile and agenda. Mostly ignored. My sense is those in that subgroup are hot gays looking for other young hot gays. Gay for pay fitness guys tend not to show up on Grindr.
But there is a smattering of GP profiles in Grindr. They usually say "boy" in the handle ... short for rent boy, sauna boy, taxi boy, etc. Usually young adults with slim to average builds. You can also view profiles from afar with the Extra upgrade and the new "rocket" (geographical location to explore) link. Many of you probably already know this.
