OK I am not talking about aaaall the different activities that make up for great sex, because obviously I don't just lay there and think of England from start to finish. But when it comes to PIV penetration, he does ALL the work! Always! He is dripping and I hardly break a sweat. The difference is quite pronounced - he goes on two-mile runs to keep his stamina and fitness, I eat another chocolate brioche and ponder on my next orgasm. Is this "how nature intended"? Is he going above and beyond the call of duty, spoiling me in the process? Am I being plain lazy? How does it go with you?
