Ok guys need some advice, especially from the gym buffs! I used to be really big and got hurt, and now getting big again. I take a pre/post workout, protein, and vitamins! When have sexing I am having a hard time getting it rock hard and keeping it there! I am a lil worried and want to fix this! Main reason I want to please my girl and I think it gets to her a little when I lose the rock hard dick! This same thing happened when I was big a while back, and when I stopped it came back perfect! Help plz
