What age must have a babysitter to bath a 15 y.o. boy?

I am not sure where you are from but it is never appropriate for anyone to bath a male or female over the age of 5 or 6 let alone a preteen or teenage boy or girl. As a matter of fact it is illegal and you can be charged for child molestation or worse. Imagine your life after having to register as a sex offender for the rest of your life. I wonder if you think it would be ok to bath a 15 year old girl? Quit being silly, listen to that little voice in your head-NONONONONONONONONONO.
