Anyone ever have issues enough with your size that you were unable to function- aka get it up? I think I am average enough and yet I have a hard time gettin' hard sometimes. I am not sure if it is a result of anxiety or if it is a real physical problem. I can get it up on my own- but have had a hard time keeping the little guy at attention when the time calls for it with someone else. I wonder if I stress too much about my size. Anyone else?
