How to: Near the edge of a bed or bench, rest on your hip and forearm and press your thighs together. Your partner stands and straddles you, entering or grinding from behind.
Why: This position offers extra deep penetration while stimulating the G-spot and satisfying both parties.
How to: Go down on all fours and your partner does all the work. Make sure to get down real low, putting most of your weight onto your forearms and arching your back as much as possible.
Why: This is one of the best positions for G-spot stimulation. It is also a great oral sex position for cunnilingus or anilingus. This position gives you both nice views of each other's full naked bodies.
