This position is not too tricky, but may require an adventurous mood. There are two versions: In the first, the woman sits on a washing machine while on spin cycle and the man enters her while standing, this way she is getting stimulation from penetration and the vibration of the machine. In places where a washer and a dryer are side-by-side, the couple can even lay on top. "Men say they like this position. A lot," says Anka Radakovich, sex columnist and author of The Wild Girls Club, Part 2: Tales from New York to Hollywood. For this reason, she cautions couples that sex in the Washing Machine position may not last long.
