Interesting fact

---

i was just watching discovery about sex and it said that a limp penis is a tense penis. because it's resticting blood flow to the rest of the penis. just thought you might find it interesting:P

hmmm... good point.

hm..ya i thought it would have been the other way around since my muscles seem to be tighter when erect:S but oh well if that's what the experts say then i guess that what it is:P

Well, in erection the blood flow into the penis is increased by the artery dilating, and the blood flow out is stopped by the vein out being pinched off. So although there is a lot more blood in the penis when it is erect, there is no circulation. (The oxygen in the blood starts getting exhausted after about four hours.)

When you think about how quicky a limb goes to sleep when circulation is cut off, it's amazing that a penis can last for four hours with little fresh blood.

I don't know how much of a contributing factor it is, but I'm sure the fact that the penis is filled with spngy tissue, and a limb is filled with bones,muscle,et cetera, has something to do with it.

Yes, there's a lot of blood in there, and most of the tissue inside just has to do basic repair metabolism rather than any heavy energy-consuming work - all the hard muscular work is being done elsewhere.

true:p and it also said that human males are the only males that don't have some sort of bone in their penis:S i thought that was interesting:S

Dont pandas have an "S" shaped bone in their penises? that could make for come kinky sex

lol or some really painful sex:P could you imagin if you pushed too hard and it broke:P ouch.
