The scene in KL is not that great. I was under the impression that the Bukit Bintang area was lined with MBs but I did not find that to be the case at all. And I gave up on the Otot-otot sauna as they don't seem to practise safe sex at all.
I got all the action I wanted in the gay massage places in Siem Reap and Phnom Pehn. The bars are a waste of time if you're looking to find a "partner" but in themselves, they are great for a drink and a bit of entertainment.
