The farther into puberty...

[kda2011]

I can cum and all... But the farther into puberty will I not ejaculate as quickly as I do now... Sometimes I cum really fast and I was wondering if it will take more time later on.

I think it just varies everytime you mastrubate. I don't think It will shorten or lengthen.

yea. like during puberty i dont think anything will happen unless you want it to, like you could go longer by going slower etc. when u get alot older like a while after puberty i think it takes longer but im not sure

I always wonder about that too because right now i can't last very long at all but I expect that will change later. Consider that most people that are our age are pretty unsure of themselves and sexually orientated things are far more nerve wrecking when you are unsure of yourself. Thats just my theory though. Don't hold me to that.
