simple, add numbers in your head (1+1 = 2, 2+2 = 4 and so on) do anything you can just to totally bore the shit out of yourself (but not so much you go soft or just start getting boring to the girl or guy as the case may be) masturbate 3 or 4 times before even doing anything or meeting up with the "person to be boned" or if you seem to always just get laid outta the middle of no where, never step foot outta your bedroom when you wake up before doing this morning ritual, then you will be ready for the rest of the day. could also practice teaching your body to slow things down, try beatin it and holding it in for as long as possible (hard to explain, you'll just have to figure it out on your own) or going through a period of doing it right til that point and stopping, waiting awhile and doing it again, it's all about mentality. once you can show your mind that it's more pleasurable to not go when it's ready, your body will follow trust me
