I think i've heard this.. Or seen it on a
movie somewhere before.. So I went and
did some research, here's what I found:
"cocaine has been reported to produce a
prolonged and intense orgasm if taken
prior to intercourse. Thus its use is
associated with sexual activity, often
compulsive and promiscuous."
"i have heard of people rubbing it on
their genitals to make sex better. Is
this true? Does it work?
It is not recommended to rub cocaine on
any exposed tissues or the mucous
membranes of the genitals. It does have a
pleasant numbing anesthetic effect but any
adulterants in the powder may not interact
so well."
...Plus alot more info where is says that
people have used it analy, or even
injected it into their penis

...Everywhere i've
read though says that this is a dangerous
practice. So while it may feel 'good' at
the time, I would rather have the less
intense experience and be safer any day!
