I really need some advice..[Mainly from quys but woman can Reply too]?

Ok... First off, if he loves you he will give you plenty of slack. I guarantee you he wasn't Superman the first time he had with a girl. It took practice. So, my answer is: Use your legs to create leverage up and down. Put your hands on each side of his body, and push up with your hands AND legs and come all the way back down (to get deep). Don't just sit down and rise up. Try to get a bounce/rhythm going, it's trial and error from there. Eventually, you'll get a fast, deep rhythm going. (FYI: Focus your weight on your hands by leaning forward and coming up, and when you come down shift your weight to your hips by sitting straight up.)
