I found that Grindr was crazy easy. But, I'm under 35 and a minority, so perhaps I fit the mold of "exotic" fun. I also have my face in my profile so I don't come to play. First day I was in Budapest, I thought my phone would overheat form the Grindr messages.
I haven't ventured into providers or their sex sauna's yet. I did visit Irgalmasok Veli Bej Bath sauan. It was nice, and on male only day, the older gents are out to play. But many play in the steam room which is far too hot (temperature wise) for my American blood.
