Verrry Wettt
My dick is 7.5 inches. What I do is get a lube (Vaseline would work) then pour half the bottle in my hand till it's dripping. Then make an 'O' with your hand (not very tight) and slide your dick in it slowly like you're fucking a really wet pussy. If you want, put a picture of a dripping wet pussy to look at while masturbating.
