Yep some / many of them screw up like that. This is why we like the guys who have experienced the unwanted sides as well as life long dysfunctional ED and Anorgasmia to man up , stand up and tell your stories so others can learn.
I tell ya some of us OLD school guys like myself were and are VERY lucky to have had NO life long problems. Ha ha LOL but guys I gotta warn ya when you are still cycling at an age over 65 you have to work with the Gear's unwanted sides
at the same time of fighting some older age natural sexual problems.
I tell you I LOVE my Cialis .... gotta keep the little guy UP and awake upon the call of duty
