>>4887810>1: Men last longer on bottom. etc...So much of this is not true. IF men last longer (I have yet to ever see anything that indicates this) it couldn't have anything to do with an "internal gyroscope" thing, it would have to do with blood circulation. Also "more powerful orgasms while on your back" is also completely presumptuous, and ignoring the fact that being on your back means MINIMUM exertion, which in males means that you have to build to orgasm pretty much PURELY on sensation (instead of increasing heart rate and overall exertion in combination with sensation). That alone could be a reason to "last longer" if you're wearing a condom.
>2: ... This also means she can angle herself so that your cock hits all the spots she likes.Unless, of course, the spot that she likes is more than a 20 degree variance from 90.
>3: Your dick feels longer. ...The heavier you are, the more it flattens out. The reason she can get further down on you is because to be on top, her legs are (usually) split, which is actually what makes her the most open, and allows her to slide all the way down to your crotch. In doggy you tend not to get as deep because the asscheeks are in the way, and in missionary her legs aren't spread wide enough (unless she's extra flexible).
