Wow I never answered this. From my end it’s multi-fold.
Surely most of you have seen the “Massage Types I Offer” section of rentmasseur with the options “therapeutic” “sensual” and “erotic”.
I have an idea, but I’m sure most people (outside the forum) don’t know the difference between “sensual” and “erotic”. So most providers will select all 3 so they show up in search results.
also, sometimes clients aren’t always truthful. Some say they want a massage but they’re chasing you around the room in a few minutes. (This isn’t everyone!)
ive even tried asking what site they found me on, but some have asked for massages off Rentmen and more off masseurfinder.
last, as @Lance_Navarroonce said, the two go hand in hand. Many clients do want some of of both; the amount of both they want is a sliding scale.
so as difficult as it can be to determine what someone is offering, it’s also difficult to determine what someone wants. The websites don’t make it easier.
the best to do is ask if someone offers what you want.
