Well, amidst the swearing, sexism, and insults to a moderator, I can repeat my last post.
No, that string beneath the head of the penis (aka the frenulum, also called the "banjo string) is not supposed to snap, and if it does it is bad. You need to go to a doctor.
Also, the original post (aka the one you are replying to) was posted on 08-15-06 at 5:08pm. To my knowledge, it is now 10-21-07. That is more than a year after the original topic. Again, I'm right and you're... in need of a dictionary?
