Stuff like this is generally done for attention and to show off in my area.Its all ooo, look at me, I managed to suck a guys dick aged 13 ( this isnt reffering to OP) and he was older, now you can all respect me for being a whore.
Srsly, although our year wasnt too bad, I pretty much know all of the year below, and they have some whory people. One girl got caught having sex in the toilets on 3 different occasions, yet it was always the boy that got expelled. It disgusts me.
I can sorta understand underaged sex depending on the people (like a sensible couple who have been going out for a while and have thought about it properly) but most people in my school have sex with their other half about a week in (well, the first time anyway, to show off that there not virgins.)
Someone else asked a whole list of boys (one at a time) to 'stay round hers' on the night before her 16th birthday, because she wanted to lose her virginity before it was legal to. Another girl said she would just give the guy she liked a blowjob at the upcmoning party so that he would go out with her. I could do this for about 3 hours.
Then again, its only one problem with people nowadays
