I'm a 22 year old male, and lately I have been having some Premature Atrial Contractions during masterbation. I have had a history of PAC's, but my doctors believe it is due to, what they diagnosed at the same time, my Generalized Anxiety Disorder (GAD). With that said, you could say it has me worried. It doesn't happen every time, but it does happen like every other time or so. Help! I need answers! =/
