The tip is the most
sensitive, and in many
respects, the most
important part of the
penis. Examples of its importance include the fact that the tip is the part that received the bulk of
attention while being the
recipient of
oral sex given by a woman (or, hey, by a dude) who can't take it farther than that without
gagging. It is, as well, the ultimate
nozzle on the
urinary firehose (technically called the external urethral orifice).
It is somewhat
fortunate, then, that it is biologically impossible to
have a penis without a tip. Evolutionary biology reveals that the earliest penises in the animal kingdom had tips. Even if you were to chop off the tip, whatever was left after the
chop would be the new tip, although it would nowhere near as
effective or
pleasant of a tip as the one that the your penis came with. Unless, naturally, you were to chop off the entire thing, but then you wouldn't have a penis without a tip; instead, you would just have no penis. Note that if you are a girl, you already have no penis. Your
vagina, in that case, doesn't have a "tip" -- I mean, what would it be? The
clitoris? The most extensive protrusion of the
labia? This is a question which demands far more extensive
study, beginning immediately.

A fellow noder wisely opines upon my medical error as to the chopping-of-it-off: "The penis extends a fair distance back within the body, even when it's fully erect, so cutting off all of the external shaft doesn't even remove the penis entirely. This is part of how "penis enlargement" surgeries work. They sever some of the connections to the muscle that holds the penis in place, pull it out, and then do some remedial action to hopefully not cause scarring/loss of control/etc." Ah yes those are some very true facts. Note, please, that this writeup is not intended to be read as, um, entirely literally correct. Do not try this at home!!
