The Mermaid Underwater sex positions? I know right, how the hell did I come up with that? Well naming sex positions is hard work. I was staring at this and the guy just kept looking like a guy snorkling, floating on the water. Then I ask myself, if the guy is snorkling, who in the hell could he possibly be banging? Naturally, a mermaid. So give this one a try. There are similar positions in all of these main stream sex position guides but they usually have something like a guy in a pushup position off of a couch. This means he needs to use his arms to hold him up. That is just not good enough. Hands should be free to touch boobs!
