In the past few weeks, I’ve become increasingly convinced that touching yourself causes a kind of under-sensitivity. And, then, when you have real sex, you can’t stay hard.
I’ve done something similar through experimentation. I do generally feel better after the “hump method”. It’s also with this that I believe that the man and woman would get the greatest sexual benefit from the man doing the action rather than the woman.
Yes modern sex positions are highly unnatural and not as satisfying. In pornography, both actors have their bodies apart during missionary to show the girl’s breasts. But actually sex is far more satisfying with deep body contact.
