hey this happened to me after taking pramiracetam, my sex drive like virtually tried up like overnight it seemed. that very same f******** night i went to bang my girlfriend and couldent good wood like the night before, after that, bam i had erectile dysfunction everytime, i had to fap to make my penis hard and i would ejaculate like in a minute, this angered her and she left me because of this.
I have had this same issue for the past 2-3 years now...... sexual performance maybe increased a little bit but I swear to everything i was a race horse and could have sex for hours the night before i had pramiracetam.
