Great sex positions: swimming
An aqua-vibed sex position that doesn't require a swimming pool or penetration!
OK, so this isn't technically a sex position since it doesn't involve penetration, but it is extremely satisfying for intense clit rubbing and is incredibly simple to pull off...
With your man lying on his back and his legs closed, lie down on top of him with your legs closed and following the lines of his. By dragging your clitoris up and down your lover's penis, you can apply as much pressure as you want while rubbing yourself against him to make you orgasm even harder.
