I like it two ways: either standing, with my jeans and briefs around my ankles, or naked on my back. I love to be standing, and have him or her open my belt and unbutton and drop my jeans, then suck me for a while through my shorts before they slide them down, and take me in her or his mouth.
I also enjoy lying naked on my back, legs either stretched out, or spread wide, flat on the bed against my butt. The guy or girl between my legs, sucking my cock and licking my balls.
Other variants are also fun!
