Well coming from personal experience- it does numb the clitoris. Thats not saying that I didnt want to have sex or wasnt able to reach orgasm vaginally, but reaching an orgasm through the clitoris was virtually impossible until the numbness ceased.
At the time, the BF and I were snorting
lines off each others naked bodies and the shit got everywhere. We bought in bulk and got a little crazy. Cocaine
makes me super horny anyway....but yeah...so...
In reference to the "knickers" comment (I say panties), its possible that she was extremely turned on and was wet, but I highly doubt that a clitoral orgasm could be reached. Cocaine on the penis has the same numbing effect, just incase anyone wants to know. Also the same goes for your (God I hate this word) anus (ew) so if someone is a newbie to butt-sex this could be....um...helpful. Those are also from personal experience.
Ahh....the good ol' days....
I miss sex.
EDIT: After reading Alienesse's post I thought I might clarify that I was not an exotic dancer at the time, this was privately between the an ex and I...LOL.
