How do you find a gay male mate?

In gay clubs, gay associations or groups, or on gay websites (either meeting websites, or social networks)

Answer

Don't try to "spot" gays around you, that could get you in a dirty mess (people are very sensitive about that). Also, it doesn't work that way.

When seeking people of the same orientation as yourself use only reputable places such as known clubs and as mentioned associations. If you meet someone through an on-line or company dating agency arrange to meet in a public place and remain in the public places throughout. Inform people close to you of your intentions and where, when and who you will meet. Keep a mobile phone handy and if in doubt - be discreet and leave their company as soon as possible so that you remain safe at all time's. If possible meet with other people you kow there as well.
google for "gay" + (major city name(Orlando, FL) and it will come up with all kinds of stuff.
