A well hiden secret , all these guys use a vacuum pump before the shot , they pump right till before the point of getting a bloated deformed look , Mandingo , Lex , Diesel etc . I have done that before for the Shock value and look . I fucked a few girls and on many occasions I get the comment " God you feel like so big tonight " and my answer usually I'm so fucking horny for you , you turn me on like Crazy" and that does the trick.....lol
