So, I was just coming to this blog to post this apology; I typed 'Male' into Firefox's address bar and hit 'enter.' I got the Google search for 'male', which included this fascinating page on foreskins, which I know almost nothing about. I'm sure I've seen them, but I've never noted one outside the movies.
The foreskin performs several important functions. Most of these functions center on making sex more enjoyable, not only for just one, but for both partners.
Makes sex feel better
Lubricates during intercourse
Lubricates during masturbation
Reduces the drop insensitivity through age
Allows the erection to grow
Increases sensitivity slowing intercourse
They sound like great things.
