Getting into the typical doggie stance, have your girl keep her legs closed and open yours around them. As well, get her to arch her back and lean on her hands rather than lean down and rest on her elbows on the bed (or whatever surface you happen to be on). To help her maintain that stance, wrap your hand around her hair and give it an occasional tug while you're having sex.In addition to hair-pulling, you can rub her spine lightly and even hug her waist while you penetrate her.
Air-Drying Your Hair
Every once in awhile, air-drying your hair can be good for it -- as long as you do it right. Make sure you use an absorbent towel to speed up drying time, and blot your hair gently instead of rubbing it (rubbing can cause frizziness and split ends). For extra volume and waves, pull your hair back with large clips until it dries.
