Baxter, I'm talking about my perspective as a woman and a Mother. I am not saying that anyone else should feel the same way as me. For instance a woman of my age who never had children, is not likely to feel the same way, so I can only comment on how 'I' feel.
I was talking to a client earlier today about the age thing and explained to him that I was a late developer (nothing to do with this thread) and in comparison, my Sister had sex for the first time at 13 and she instigated it (traumatised her poor 13 year old boyfriend she did). So, by the time she was 18, she had 5 years experience behind her belt, whereas I had one month.
We all develop at different rates. Some are more streetwise than others, some have had no choice, but to be more streetwise than others. Some people are attracted to older men, some to younger men. My point is.... we're all different, but... you can't know that by looking at someone's profile and for some there may be a concern that the lady is pushing herself before she is ready, while others may just ooze sex appeal. I don't know, but I don't think it is unfair for some to be concerned and choose to avoid those they are concerned about.
I know of a few girls that started young and they are amazingly switched on, well adjusted, intelligent young ladies and could teach me a thing or two, but... that won't apply to all of them.
The other thing is that I don't pick up the phone and call my clients, they call me, so if a 19 year old books me and pays their hard earned cash (or Uni fund money) to see me, then that is their choice to do so. No one has made them make that call or made them give me the money, but even then, they may be doing it for the wrong reasons and I would not hesitate to give a young client his money back and send them on their way, if I didn't feel comfortable with his reasons for being with me.
I can tell you now, if someone went to join the forces and they were not right for the job, they would not make it through basic training and they would be sent back home. It's not as easy as you think.
