I've been having trouble w/ premature ejaculation for a long time. My first kiss when i was 20 years old I ejaculated all over my pants I was so embarassed. I thought this was normal for a young man but im 31 now and it still happens. My wife just touches my penis and it erupts... I feel like the kid from american pie.

This one time my dog brushed up against my leg and I ejaculated..

Help me!!!!

Also, my penis is only 2 inches long when erect could this be the problem?
