Erotic in my words means "sexually stimulating".  It's vague enough to leave an out if used in an ad & she chooses to upsell or rip you off.  For instance, "Erotic dancing" could mean just a sexy dance, a dance with stripping but no contact, or dance with stripping leading to actual sexual activity with contact.  How far a particular lady is willing to go is another matter.  

I'm going to go afield & assume that you're shopping & have seen this somewhere in an ad.  
Some might use such terminology in advertizing in an attempt to be discreet.  Frankly, if you are shopping, it takes a huge amount of time & energy to shop elsewhere & then search for reviews after.  All reviews are not created equal.  TER is client driven...  we pay...  so reviews tend to be more reliable in my opinion.  Other sites I am familiar with are "ad sites" and are provider driven (providers pay for the site).  I did invest the time & have found a large difference in reviews between the 2 in my area.

Yes, it means if you want to use TER reviews you must pay for VIP (at least some).  VIP is far less costly than even one spoiled date.
