I think that most, if not all, long term punters go through different stages.
I started out doing mainly Soho walk-up punts - 10 minutes French and sex, wham bam thank you Ma'am.
I progressed to some newsagent window "indie" girls, more expensive, but less rush, so probably 20 minutes for ( covered) French plus sex, and nicer surroundings. Still did some walk-ups though, and discovered Shepherd Market. At this point, OWO was unusual (the French flat with Lily and Josette off Soho Sq provided it), and anal was like hen's teeth (Jacky, first of Lisle St, then Peter St last at Shepherd Mkt) was one of the few. Kissing, forget it....
Then Soho Cottage in Duck Lane and Les Girls just off Berwick St came along, and you paid for time, not for particular services off a menu (at that time in Soho, some girls charged extra for things like changing position.....), and stopped doing 15 minute quickies, when the legendary Paige refused to do less than a 30 minute service. Much nicer surroundings, and you could look at their rota and phone in and book the girl you wanted to see at a time that suited you. Both places had some really good girls - Helen (who left and came back as Heather) at LG was amazing, for example, and I started booking longer punts with her, and later, with Paige. Tara, at Soho Cottage was great too, and went to Hollywood to have a brief career as porn star Rose Petal.
Ultimately, these establishments couldn't survive and I started to punt less and less in Soho, using recommendations from Fr's on PN to book indies. I also discovered Sacred Rose Parties in Earls Court, and had some great times there.
I tried out some other "managed flats", kind of in the Les Girls mould, like Debbies, HOD and the Bunny Lounge, but since that time, my punting has been with indies found on the minefield which is AW (greatly assisted these days by the good gentlemen here, of course) and the occasional party.
I don't think the content of my punts has changed all that much, except that, of course, DFK and OWO are now the norm, and anal is much more widely available.
Thanks to this site, I'm now paying less for punts now, finding good value and punting on average, about 5 times a month, which is the perfect ratio for me - at my age I don't really want more than that.
