I experienced Kasai Massage last month. The atmosphere was low-key, unlike the flashy soapy shops. The masseuse was calm, skilled, and focused — started with a full oil and body-to-body slide to warm things up, then shifted smoothly to prostate work. It took about 90 minutes total, and I walked out with a level of relaxation I didn’t know existed.

The @581byNana spot is definitely less polished, but people swear by it for efficiency. A friend described it as “what it says on the tin” — no extra decor, just a private room and someone who knows what they’re doing. He paid about 3,000 THB but told me afterward that the focused technique was worth every baht. Not for everyone, but if you're just looking for the experience, it works.

Prostate massage in Bangkok isn’t common knowledge, but Kasai is usually the one people validate. What I'd say is go in with your body relaxed — limber up beforehand. And don’t expect the same tease and romance of a happy-ending massage. It's more clinical in the best possible way because the end goal is total release, not prolonging the tease.
