13 is fine in my book, I would bet some 13 year olds can tell you things about sex that some adults are not old enough to hear. Obviously it depends on the person, some 13’s can be more mature than others.
I have been online since the internet first existed. When I was 13 years old I used to go in to BDSM chat rooms to play pranks on some of the horny creeps you find in there, and all kinds of other things.
Also, 13 year olds will have valuable information to share on many topics, for example video games. You can be as good as you like at video games, but facts are facts, a 13 year old will kick your ass at any game 99% of the time. They can also give you valuable insight on things such as new trends, new slang words, and keep older people in touch with what it’s like to be that age. In my opinion, if we are going to talk about how being bullied in school can lead to suicide and other such topics, it is vital to have some members who are them selves still in school, and still in that enviroment of school politics.
My parents where once 13, but by the time I was 13 they where totally out of touch with what its like to be that age. even though you remember what it was like as you get older, there is still a lot that you forget. At age 27 I still remember what it was like to be 13 quite well, but I would be willing to bet there is a lot that I have forgot about.
I don’t have kids of my own yet, but if I did, I would much rather they spend time on fluther than many other sites.
Also, going on my own experience, I am more or less identical at age 27 to how I was at age 13, the only change is that I have a larger vocabulary and can put my point across better. I still have a healthy dislike for authority, I still enjoy many of the things I used to enjoy as a teen, and when I see a question about teenagers, even though I am 27, there is still a part of me that tells me “they are talking about you”. Perhaps, because deep down im still the same person as I used to be, and still feel the same about many topics.
