Why?

I'm not sure of the reason men have a foreskin. I lost no sensation with it's removal, in fact, I'm way too sensitive and suffer from premature ejaculation especially if I'm a bit pent up and it's been a while. After I cum (usually two or three times within a couple minutes), I seem to lose my libido and cant be bothered to carry on as the bullshit porn industry tries to suggest is possible.

I am only guessing, but our origins began on the plains (and in the shrubs) of East Africa and, (probably?) the foreskin would protect the sensitive part of our bodies as we ran through the brush. Entering a vagina (I'm still guessing) would manually pull the skin back. Maybe?

I've never "fired" multiple times within minutes. But I am very sensitive "there".

From what I've read, the bullshit porn industry uses drugs to keep the "thing" going. The "endurance" often referred to is usually the guy's ability to take a lot of that drug to keep things going. Again, from what I've read.
