Guadalajara is a great city for culture, food, markets, etc and has a lot of good looking guys there. I am sure that the rent scene exists but I never really saw that when I have been there. There are several gay clubs for music and dancing. The few stripper bars I went to seemed to be more geared toward women clients and the dancers tended to be beefy--actually slightly overweight guys. Maybe there are other clubs that have more attractive dancers and I just missed them.
I would definitely visit if I were you though--lots to see and as least as much potential in terms of guys as Mexico City(which I love).
