I found out I can get erect while going through the hump motion. Just excersing my hips will make me erect. Are you other guys able to get up doing this?
Sometimes, depending on the day/mood, and usually in bed. I'm pretty easily aroused. Loosely wrapping my fingers around my flaccid cock and rhythmically banging the edge of my hand against my balls in a classic jerk-off motion generally causes my dick to become erect inside my hand.
