Im a 16yr old girl and i know this is really mean but i just do it for fun.
When i go to a public swimming pool, i call over a random boy, who is about 13 or 14 who is in speedoes.
I start talking to him about sex and my boobs and stuff, and then i just jump on him and hug him (im wearing a bikini). I make sure he feels my boobs and that his dick is touching my vagina and i hold him there for a few secs.
Then, while he's swimming away, I go under water, take of my bra so only he can see my boobs, and hug him again.
Then I let him go and see his reaction.
Normally he would get a real big erection and I would be able to see a glimpse of his balls and dick. and everyone sees him.
I know it mean, but i sometimes cant control myself.
In any event, she ain't one.
I think maybe you have a low self image, boys your age or older are threatening and so you like the younger ones. It is okay but try to approach older guys more. Trust me if you do the bit with your suit you will have their undevided attention.
