Yes. In fact the Department of Motor Vehicles just came out with a study in January that cited the increase in safety for all travelers when at least one person on the highway is being sucked off whilst operating a ton of metal going 75+ miles per hour.
The article goes on to describe how performing '69' or blowing the guy driving increases road safety - but I don't want to stray too far from your question...
The mechanics of blowing your man while he's driving stick are much the same as if he were driving an automatic. The only difference is, at times, your face and his arm are going to be jockeying for the same bit of real estate. During those moments, when the laws of sanity require him to shift gears, gently remove your lips from his wang and patiently wait. Oh I don't know, 2 ½ seconds so that you guys don't smash into a CVS or pick up truck. Then when safety has resumed go back to tending to his fleetingly neglected shaft.
So in conclusion, yes, you are right to point out that two things cannot occupy the same space and thus oral sex and a stick shift can create an issue, but at the same time, I hope my illustrating how reasonable it is to pause sporadically -- so that you and he may continue living -- makes the whole conundrum a bit less troubling.
And always, seat belts. Nothing worse than being pulled over for speeding while still blowing a dude AND getting a ticket for not being buckled up. Quite embarrassing.
And always make sure your next of kin card is updated so the hospital will be able to identify then when they find you broken and battered beside the road because he swerved around. Not to mention they will have to re-attach his severed penis because you bit it off when you hit the tree/semi/car/guardrail doing this stupid stunt. AND of course, the cops will want to talk to you once your broken jaw heals for killing that family of 7 in the minivan, but hey, you got your guy off in a 2000 pounds weapon hurtling down the road at 55 miles per hour or faster, right?
Seriously...if you can't wait to give your guy a blow/hand job, PULL THE FREAK OVER. It's not worth the risk for that moment of pleasure.
Oh, the vivid pictures over this one! ;)
Thought provoking ... yes ...
I say safer ways can be fun...why not rock it old school instead? Pull into a McD parking lot after dark, crank Led Zeppelin's Kashmir, climb into the back seat and get it on....
