Just took a Viagra 100, I really need to get to the bottom of this damn erection problem. I wanna know if it's a blood flow problem or just hormones. I figured if this viagra doesn't work, i got a blood flow problem. What makes me also think this is I've had a pain right below the base of my dik on the left hand side for prob 8 months now and it hurts if a girl pulls on it realllllllly bad. either way whats the max dose of viagra, I want to take the most I can without hurting myself just to see if this fker will wake up after being half dead for almost 3 yrs.
