I'm nearly 13 and I masturbate a lot. I can never seem to make myself c*m though. I've felt close to but I nevar have done. I've had orgys too but I can't get a dildo or anyfink cause I won't be allowed to so anything easy will be very appreciated. (I'm a girl by tha way.)
At your age, your body is still in the puberty phase. Not being able to cum is ok, it will happen in time. It just means your body is not quite at that stage. Enjoy the experience and eventually it will happen.
