Well PFR, to be honest my friend didn't blame the group members who were often in long term relationships, but would find groupies and publicity seekers in their beds, waiting for them at every stop and generally making a complete nuisance of themselves.
He also mentioned that music "personalities" had to be extra careful due to the chance of allegations of impropriety being brought.

As I said on another thread (now deleted), sex can be a potent weapon.
It is not as simple as it seems.
I find the furore over knee touching etc an idiocy.....men are hard wired to try it on.....in my youth if you took a girl out and didn't make some attempt at sexual intimacy most would be deeply insulted.
I remember one girl I took home a couple of times, I was very attracted to her, but decided just to play it cool.
She dumped me, years later as a friend, I asked her why.

"I Thought you didn't fancy me" she said. :0)
