My first punt was with a Romanian who wanked me so much I popped in 10 minutes after an unenthusiastic covered BJ.
I had booked an hour, but changed my mind when I got to the room, the stupid bint asked me how long. She was not really the expected stunner - young but no oil painting - so I went for half an hour.
It was then after coming. that she said 'come only once'.
Being a bit naive and nervous, i complied, so all in all not a great start.
Left it a year and a lot of wanking before i tried again and lots of research into the process, expectation and how to be in control.
After a flurry of one hour punts, I sussed that half hours suit me best.
I've had no shows, bait and switches, but some really fab punts.
But my advice is thinjk about it, wank a lot and listen to the advice, not your knob.
