I had a girlfriend who bought a product that was called "Mister Prolong"..It was just a numbing cream so I couldn't feel anything.
She was so damn hot..I mean almost a perfect 10, I found that turning off the lights ,so I couldn't see anything worked better.
After 45 minutes or so, I'd just reach over.. and turn on the bedroom lights, and it was over in about 3 minutes after that.
I didn't like the fact that I couldn't feel a thing...Condoms , combined with that stuff feels like you've had a temporary back injury, and have gone numb, right where you don't want too be, when you don't want too be.
