how to cum
You can't exactly force yourself to cum - at any age. It simply occurs when it does. It will generally "becum" more common as you progress through puberty. I'm 15 and gay porn will always give me and erection. However, it's never caused me to ejaculate. The only time that I've ejaculated while awake was when a boy on the internet began to send sexually explicit pictures to me. Ejaculation is controlled by your nervous system. I can safely assume that porn was less effective simply because it wasn't enhanced by the emotional connection that I had built with the one person.
