For me it's quite simple.

It's not clock watching as it's always me that does this, nor hygiene or bad manors,
as I have never experience this with any of the ladies I have met.

What has turned me off in the past (sorry no reviews), was when the lady has said one of the following:-
"I'm quite small - but you're very thick!" (hope she wasn't referring to my intelligence!);
"don't touch my face, I don't like it";
"I don't like my hair being touched";
"don't touch me their";
"I'm very ticklish, if you touch my nipples like that, I will thump you".

Fortunately the above hasn't happened too often, but when it has, it has been a major turn off,
with the little fella refusing to come out and play.
The strange thing was that it has always happened with ladies that are well established and have had a lot of posirive positive reviews.

Always thought it was just me, so decided not to submit a review.
