About any position that gets my cock in a woman's pussy is a good position. However I do enjoy missionary. I find it a tremendous turn on watching a woman's facial expression when she knows I am going over the top and I am going to cum in her. Very hot, very erotic, very primal. Missionary is a great position during the refractory period after an orgasm. I love laying there with my cock still in her after I have blown my nuts into her. A little conversation and play and then work the cock and get it hard again and get the second round going without ever having broken contact. Cowgirl is also pretty good for this.
