The problem I have with it (and some here are going to shoot me down for saying it) is that no matter how you try to dress it up or excuse it, it is still talking about something which is not only illegal (reall, who gives a shit about that!), but actually really very, very sick. And if people need to work through experiences from their own childhoods, then the right place to do it is with a suitably qualified counsellor, not a working girl.
The problem is, I think, that girls participating in age play does offer tacit approval, which is tantamount to condoning it.
And the real problem which stems from that is that these "fantasies" are fed and reinforced.
We all know how sex works, especially those of us who escort. Anyone who knows even the smallest amount about psychology knows how strong sexual reinforcement is, and whether girls know it or not, that is exactly what they are doing with a guy no matter what the situation. Probably more so on cam or chat than in real life, actually.
So by speaking about these extreme taboo subjects, girls are (perhaps without realising it) reinforcing the ideas in guys minds.
Now I am not suggesting for one minute that all these guys will then go on to abuse children in real life... but I'm also not going to say that guys who do that would have done it anyway, with or without extreme chat.
I'll bet my very last dollar on the fact that the vast majority of guys in prison for doing that very thing will have a history of using porn and sex lines to feed their fantasy.
And if girls are doing it, then they need to realise what it is that they are doing.
If you think I am talking out of my arse, read this article:

... or one of the many like it, which shows a clear and irrefuable link between child porn and paedophilia, and an absolute and demonstrable link between guys who use child porn (which includes direct chat) who do actually offend against children.
