Photos 10 and 10a show some interesting sitting sex positions -- once again fun for a variation on routine sex, but probably not something you'd want to do every day. She can lean forward as far as she likes; if this lowers her pelvis, he can simply widen his stance so that he can still enter her comfortably.

She places a foot on each of his shoulders, and he enters her as he leans forward - this means he can push deep into her. The book's inclusive, deftly illustrated guides to manual, oral, vaginal, and anal sex positions are our favorite part. She may well love the stimulating feeling of rear entry sex on her G spot. This time the guy's kneeling, although once again this is just a matter of adjusting the height of the two partners so that he can enter her easily i. Photo 8 shows an easy position in which to enjoy rear entry sex: You can see yet another variation of the possibilities of this position in photograph 4, where the man is able to pleasure her with cunnilingus comfortably and easily. Photograph 6 shows a variation on the T-bar with added lift: That's where Clare Cavanah and Rachel Venning come in. You can see this taken even further in photo 7: This time she has also the possible excitement of dangling her head backwards over the edge of the bed, which some women find hugely exciting - it gives an extra rush of blood at the moment of orgasm. And though she might need something under her feet to support them and prevent any strain on her legs, and he might need something under his knees to protect them so that he doesn't get sore knees, all in all it's a wonderful sexual position. As always, these things can provide new sensations due to the different angle of penetration. That's great because cunnilingus isn't always something the easiest or most comfortable sexual pastime, but this oral sex position renders cunnilingus into a delight for both partners. Although there is no photo of it, you can develop this position five by having him part her legs and hold them wide apart in a V shape as he thrusts deep into her - it's powerful and sexy.
