I don't know why so many boxes are checked S&M. My best guess is that some providers will do light S&M even though they are not doms and no S&M takes place during these sessions.
I think in the past, they had seperate ratings for S&M sessions because I know that when I had many nurse role play sessions, high performance grades were allowed even though nothing more than a HE was done. That has since changed.
Again, the vast majority of people here to plain vanilla escort sessions so there just isnt' that much of a demand for seperate reviews on this.
Hey, I love role play sessions with couples and I hardly ever see any reviews of people with MFM sessions but when I do, I find them fun to read. Not to change the subject too much but from what I have heard from the couples who see guys, the men are so homophobic that they won't write reviews.
