Just looking back and came across this comment:
"Battykoda - It's just that if you are agreeable to him watching porn, I don't see that it is such a big leap to him ringing a hotline, even though that involves interaction with someone else, it is essentially interaction with a fantasy anyway, because nothing is going to come of it."
That sums up my view - nothing will come of it - apart from a sting when the bill comes through.
"If I were this guy, apart from the issue of the cost involved, if my girlfriend were accepting of me watching porn, it wouldnt be a huge leap to think that she might accept me using a hotline too. They are just another side of the porn coin, like getting a lap dance in a club or whatever."
I don't fully support that view - as I've said, on the phone (while it seems more personal to many) it's just fantasy - Babestation cannot get below some underwear (OK, can do with a sideways view, but frankly not as explicit as Razzle or most online porn).
Going to a lap dance club is bound to be a trust issue, as the person is only at arm's length (or less), and could be "picked up" (for a date) if the two people 'clicked', though I suspect many times when asking it would be wishful thinking on the guy's part and "oh no, not another tosser" in the girl's head.
