I think it is not much to ask to know how a bank wire works.

Most exchanges accept bank wire (at least Mt. Gox and TradeHill).

And for the sponsoring of girls: I didn't mean the boy has to give them as gift.
He could simply say: give me 50 bucks and I'll exchange them for you into bitcoin.

This isn't really that hard.

(BTW In most / a lot of relationships this is the case anyway...the guy does the setup of new technical stuff and shows the girl how to handle what she needs (unless she is smart enough to do all by herself))
