My first experience was when I was in Sec Sch... Still remember my god-bro who brought me to Geylang for my first experience with an FL (previously lost my V to my friend's sister, and that was it). It was behind a coffee shop, under a sheltered carpark.
I was super nervous and drank a beer (regret). Maybe it was the alcohol, or maybe I was super nervous, my little bro couldn't stand. Luckily the Thai lady was very patient and sucked me off till I cum.
Like what the other bros suggest, the best is to go to a House. A bit more paiseh, but at least got some assurance. Also don't be pressured by the uncles, just walk in, see, sit if you want, than choose the girl.
But 1 thing I don't like about houses, is they keep on calling the room (maybe is suay) if you reaching your time, so normally I book 2 sessions to fully enjoy.
