Erection Mass not always the same
I want to know why my erection mass can be completely hard,big and erect my first ejaculation? Then on my second ejaculation my erection isn't completely full,hard and erect.it just seems semi erect the 2nd,3rd time around.The main question I want to know also is that are there any vitamins,fruits,food,and beverages that I can take or eat so I can maintain my strong rock hard and fully erection like I have before I have sex with ejaculation number 1?If so what are the names of them?
