Many of the massage providers (esp. those listed on Eros like Mary, Rebecca, Christy, Amanda, etc.) list a base fee for the massage, but they mention that "customizations" are available upon request at the meeting.  I've often wondered what these "options" are, and how much they cost.  Most of the reviews refer to the "options" but do not elaborate.  Also, I assume that the customizations available with one lady might differ from those of another.  One hobbyist went so far as to state in his review that he would have liked knowing the options before his appointment so that he could be sure to have enough cash.  Unfortunately, he didn't list the specifics in his review either, so yet another person must go in unprepared.  Sorry for the venting...anyone with info on the massage providers in Philly please pass it on.
