And from the point of view of somebody who does offer and enjoy it, I can truthfully say that in an average week/month I don't get asked for it in more than 20-25% of bookings at most. It's not the extremely niche service that it once was (largely thanks to porn, I suspect) but it's still far from an everyday thing even for those of us who would happily do it far more often. I can't imagine anybody who doesn't do it is missing out on work.

i dont like it..
and many men dont like it...
it wont affect your work at all,its just like not offering other things,its all choice and taste..
but even if you were to make more money you would be miserable,so what you dont know you wont miss,i find men still see a new girl, even if this is what they like and know you dont provide it..

this is true, there are clients who really like particular services but will still go to girls that dont offer them if they really like other things about them xx
