What an excellent idea for a topic. Nice one Sam!
A lot of negatives I read about in other people's reviews turn me on. However I don't know if I'd feel differently about it if they had happened to me. A few things that have happened to me personally on punts that can only be marked down as negative when recounting for review purposes yet turned me on at the time are as follows:
* Romanian girl in Sudbury Town that Steve2 recommended to me (she was good). There were two negatives. First one: I fucked her in a room divided in the middle by a curtain. The other side of the curtain was another prossie and another punter would come and fuck her whilst I was still fucking the one I had booked. Second negative, she answered her phone and was in discussion with another punter whilst I was fucking her hard from behind. Both massive turn-ons!
* Being tossed off by an Asian girl in Marylebone, when her room-mate (another cute Asian chick) walks straight into the room, barging in, heads past us and collects some fresh towels from the airing cupboard.
* many times when I've punted in really shitty areas where I fear a little for my own safety. What an adrenalin rush though! It makes the punt better as a result!
* language barrier. This is something I encounter often. The negatives are obvious - not being able to have a conversation with the girl, her not understanding what you want from the punt (positions, and so on). The turn-on is the sexy accent, so thick it almost sounds fake or over-the-top. This aids my youth-harboured fantasy of fucking a Bond girl.
