As a gay man I preferr gay club. But, most of them allow only male avatars; this is good but don't have to be a fixed rule.
For this reason I like Klub Kermesse (a pool on the beach) that is a gay club but open to all open minded ppl and without any pornographic element: http://maps.secondlife.com/secondlife/Ruby%20Dust/216/75/25
Another club I like -but it's strongly reccomanded only to gay adult male ppl- is TRAP-hot club for hot men. It lie on a skybox over Beach Paradise N.5 http://maps.secondlife.com/secondlife/Ruby%20Dust/216/75/25 and we can reach it by teleport we can find on landing point. As per some pics into the club I suggest to no-gay ppl don't go there if they don't agree with gay hard sex XXX pics.
