Don't worry Chardax, your ok mate.

Sometimes you have to ask some questions to converse otherwise the connection/ situation could be uncomfortable.
The girls are generally young, possibly very shy and all so polite, they probably won't ask anything personal about you.
It's great when they do though- ie Maki and Toshika with me

Don't forget you are two strangers- absolutely nothing in common at the first meeting, and you need to some sort of connection in that 1hr other than the sex.
Fli is correct to advise them to be cautious in revealing more than they should.
You have to tread a fine line as to what is small talk and what is perceived as more.
I would hate to think the girl is uncomfortable and think I was stalking her .

I suppose for all we know they could be telling lot's of porkies- they are good at every thing else- aren't they ?
