#1 Try the "stop & go" By going up and down slowly and when you are about to cum STOP what untill you can touch your penis without being on the verge of orgasum and then do the same thing untill you want to cum, Then just before you cum go verry fast.
#2 Try Anal masterbation stick your finger up your anus and bring your finger pull the tip of your finger to the back of your anus and rub while masterbating with your penis. (be shure to have relaxed your anus by laying down and rum lighty the rim of the outside of your anus or by masugeing your butt cheakes)
#3 While masterbateing normaly when on the verge of cumming stick you WELL LUBED finger up your anus.
#4 Masterbate normaly but squat down with your ass as close to the ground and legs as fare appart as you can (untill you fell your anus "move or opening some).
#5 Sit on your heals and a when you are about to orgasum pull your butt cheaks appart with your heals.
