Dating more than one person at a time. Opposite of 'Serial dating'.

From the definition of "parallel", meaning more than one thing happening at the same time, and "serial" meaning one thing happening at a time.
I only date one person at a time, I'm not into parallel dating, I'm a serial dater.

When a guy tries to "park" his dick in a girls mouth horizontally, cheek to cheek. It's a tight space and there isn't always a lot of time to back up, pull out and then maneuver until you're all the way in so if that space doesn't work, find one that will.
"I know it's a tight space, but I always have to back up and pull in a few times when I parallel park. It's too hard to get it all in on the first try."
