Just wanted to bump this for anyone else interested in more anecdotal evidence from everything being peachy KL.
It wasn't until a friend in Chiang Mai said "Wow...you're comfortable going to Malaysia?" that I even thought anything of it. I think I more psyched myself out about some horror story at the border searching my phone from Grindr.

Anyways, had a great time with some of the local guys via Grindr. Hell it was quite obvious in most cases as at the Ritz there's typically a hotel lobby staff guy waiting around the elevators seeing the comings and goings.
On Sat night I met 2 friends who brought 2 more to Marini's on 57 and they were trying to convince me to go to some gay club not far (I didn't).

I don't think I'll go back to KL anytime soon, mostly because it was boring, not for any social reasons.
