Uh...What do you say to this?

I've never been at a place with bellydancing where you tipped the dancer directly by putting money into her clothing.

Now, I haven't been many places with bellydancing (live performance annoys me while I'm tryingn to have a nice meal since it makes socializing with my tablemates difficult) but this would have surprised me. Is it common?

That said, the appropriate reponse to his question would have been:

"Ask her, if she is fine with it then it is ok since the important thing is that all parties consent. Though if you end up with a disease the cost of the medicine is coming out of your future allowances."

Finally, I don't see what's wrong with objectifying people. It is the only way we can incorporate into our awareness people and things of whom we have no intimate (platonic, of course) personal knowledge. Sexual objectification is just a subsection of that. Of course, acting on objectification is where you run into issues.

It is very much a primal instinct, I'd say. And we do it to hundreds of people in hundreds of ways every day, male (see the Annie Leibowitz thread) or female.
