Very funny LOL.
To be honest there are many that will allow you to do this, you just have to develop that comfort level and ASK THEM. If you don't ask, then you won't receive. Remember you have to take it slow and see how they react ... of course there are others out there that will probably do it if the $$$ is right or just don't care and don't really get into it.
Of course there are many factors, YMMV being the main and of course if you weigh somewhere in the range of 300+ lbs and she is 99 lbs soaking wet we could have a problem.
Don't ask me for lists.
