I think she's trying to say she'll be you dinner companion, and if you're lucky, she may give you a non-sexual massage. If you ask me she's completely deluded. Why advertise on adultwork if you have no intention of offering sexual services?
And why does she show suggestive pictures of herself if everything is non sexual? Nuts!
I'm tempted to send her an e-mail suggesting a night at a concert of avant-garde music, and see what she says. But I'm not quite tempted enough to bother wasting my time like that..
