So, in Chase's article on the adapted missionary, he suggests that in order for women to consistently reach orgasm via penetration, the man must keep a good rhythm as he's fucking her. The problem I've noticed with this is that women also like "rough sex" more than anything else. This typically includes fucking her very hard and fast. Unfortunately, when I do this in adapted missionary, not only do I get tired very quickly (despite the fact that I'm in good shape), but also, it's almost impossible to keep a rhythm. So is it better to take it slow and keep a rhythm (i.e. about 1 thrust per second) or to go hard and fast but also ignoring rhythm?
On a related note, it's also very difficult for me to tell the difference between when a women actually orgasms, and when she's just feeling a lot of pleasure during sex. Additionally, I hear that it's very common for women to fake orgasms. Knowing this, are there any surefire signs that a women actually orgasmed? I don't want to directly ask her because I know this will cause her to feel pressured to orgasm, which will in turn make it all the less likely to happen.
