Stroke is VERY important.
You don't want him to start out with the
-dikk jackhammer stroke. Or the XXL eggplant cervix crusher.
He has to know what he's doing or you will be bored/irritated/frustrated during and after. Sex is supposed to be a stress reliever.
You want him to tease you, get you hot, find the spot, and knock your socks off.
You want him to make you feel good and not just use you like a RealDoll(tm)
You want him to find your spot and stay on it, and not keep slipping out or falling off like it's his first time riding a bike.
But the only good thing is if he can't stroke and he has the appropriate size you can ride him, get yours and bounce.
