Oral Sex and How you master the game?

I recent order online gaggless spray and wet mouth mints to help with my problem lasting long when giving head. I know what your probably thinking not the self proclaimed freak. I don't get complaints about my head game but I feel like I can do a lot better with putting the whole thing in my mouth with the balls mind you I have a small mouth. I'm try these products out next and tell you if i reached my goal or not wish me luck.
