i dunno dude...odd enough for me..i have erection problems myself...only the problem is not getting it up, its getting it to go down...i pop boners at the oddest of times...i have a huge sex drive i guess...me and my girl used to do it 2 or 3 times a day and id still have to spank it once or twice...but we cant do it that much anymore..(something about her inside being bruised from all the beating , so were giving it a brake to once sometimes twice a day with the occasional anal )
