I can't speak from experience as a punter, but I can talk with experience of talking to many, many men post booking.... From what I have witnessed 1 hour is the minimum.... 90mins to 2 hours the sweet spot.
From my experience, when I started out punting, I will book for an hour. Over time, I find that two hours is best as you don't feel as rushed. I know a few WL's that have enjoyed the longer session.
1 hour, enough time for a massage to relax and enough time to have some fun. I like to
I used to book 90 mins with a couple of regulars - great sex and can do two shots.
