No camera tricks, but they are ACTING. It is not realistic.
Fantasizing can be enjoyable and alright, it can also be unhealthy. Too much fantasy leads to unrealistic expectations, too much fantasy leads to too little interest in the real world.
Natural does not mean healthy. Normal does not necessarily mean healthy. The liberal mentality that, because they are curious it is alright to explore can lead to abuse. Why? Because they are not READY to explore. Just FYI, I do not mean punishing them for touching themselves, but I do mean that buying them things to 'help' them or encouraging them to go outside themselves for pleasure is beyond what they are ready for at that age. Just because you have feelings does not mean you should follow them and, imo/e, at the age of 13 you are extremely vulnerable to the mentality that, if it feels good it must be good. Therefore, to be good I should endulge in this good feeling. Thus anyone that gives me that good feeling must also be good and I would be wrong or bad to deny it. Plenty of younger teens end up promiscuous because of that line of thought, they also end up mothers and diseased. Not because Mom hid the truth, but because Mom said, 'go ahead honey! Enjoy! Don't forget your rubbers in the rain ;)' Thing is, those don't feel good, so they must be bad.
I simply, completely disagree with the last bolded statement. 13 is too young and impressionable for that sort of free reign.
Do you have children?
I thought you sounded way more rational than I would've :p
