So...nothing against gayness. But have any bros found out a little too late that a punt was a boy instead of a girl? Or is it pretty clear in HK by signage?

If you do walk in, can you just walk out without paying?

I'm new to punting so sorry if this is obvious to the vets...

PS. Out of morbid curiosity... how "anatomically" correct are these Thai Boys/Girls? Not that I would try it, but just curious to hear any stories...

This is a really tired debate that pops up too often. Some guy goes to a WG and then thinks she might have been a post-op ladyboy. Then, there is tons of discussion about size of feet, adam's apple, hands and depth and structure of pussy, pitch of voice, etc., etc.
I think the best advice is to keep an eye out for reports to see if any other note girls as possible LBs and avoid them if you are concerned. Different WGs react different to the walk-out depending on the stage of the game. Obviously, if you you've showered and she's started the routine, you will likely have to pay something if not full price. If you decide before the clothes come off, some will let you walk, but most will probably want something. If it's a $350 girl, maybe a $50. Some want $100. Don't get bullied, but be erasable.
While there have been some that said they thought their HG was a post-op, you are far less likely to find one in the HG section than a WG.

Best to avoid Mixed or Thai girls that offer anal if you are concerned about it. Less likely that a local girl offering anal would be a post-op, but there's always a possibility for anything.

Really? Why are you worried! Enjoy both holes and fuck them hard! As long as they are post op and not hanging. Some of these lady-boys make beautiful women! I will have to post about the time I was drinking in Penang and started talking with 2 girls at the bar, next thing I take them back to the room forgetting to do a package check! I never touched or saw any package...they kept it discreetly wrapped and where saving up for the op! I felt bad. What should I do? Kick them out or ass fuck the hottie! Well her pussy smelled like shit is always the joke with my friends who know me! They double wrapped me with raincoats and I pumped out a good load with that tight "ass pussy"... Nobody drops the soap around me anymore!
