Stating the obvious:
This site is very popular. Anyone could could be reading and posting on here.
Threads which seem to encourage people to talk about sexual behaviour in preteens, probably aren't from a concerned parent and for many, many reasons, it's not wise to go into great details about your own exploits and make out that sexual activity in under 16's is no big deal.
Not a TAAT, as there's been loads of threads like this, but they seem to be increasing in number and frequency.
