TIPS: Neither on top sex positions range fro easy to difficult depending on your abilities, dolls weight, and your dolls ability to still hold its positions securely. Some times its good to add pillows under your doll to get a bit more height, support, or proper pelvic angles for better penetration. Many of these positions take the time and "PRE" planning of your dolls to fully enjoy, but all are attainable, and very enjoyable I might add.
