Oh it does not cause priapism.. thats such bullshit.
Ive used Cialis for three years now a coupel times a month (I use it before the GF and I go to swingers parties).
I have never had any problems with priapism.. and never have any problems ghetting hard when Im not usingit..
The only side effect is my nose gets a little stuffy and Iget insane pumps in the gym... an of course my girlfriends pussy and ass get REALLY sore.. but she isnt complaining. LOL.
