BJ - skin up and down. When she closes the skin and tongues inside, my eyes flutter. But to make me cum, I need her to open the skin up and worn the inner foreskin and frenulum rhythmically.
HJ - skin up most times. That simulates what I have always done, rolling the skin up and down without touching the head. But for variety she can sometimes lube up the glans and hold the skin open while stroking. Generally it's either/or for me. I find that lube ruins the "peeling" sensation between the inner foreskin and glans.
