In my opinion,
A HUGE cock is nice to look at.
A HUGE cock is fun to play with.
A HUGE cock is nice to take the head in my mouth and lick and suck on it.
A BIG cock is amazing to have stretch my asshole and fill my ass.
But,
A HUGE cock makes my jaw ache after sucking it for a long time.
A HUGE cock wants to pop out of my asshole when it gets to stroking long, hard, and deep.
However,
A Small cock is incredible to take in my mouth, lap it with my tongue and have it shoot a load of cum on my tongue where I can roll it around to savor the flavor before swallowing it all down.
Size is really not that important, as long as it is HARD.
