Just a question to all the guys who claim stuff like your wife looks bored and never makes a sound with you. Have you ever considered trying to improve yourself instead, i.e. acting more masculine and learning how to "take" her like a real man, losing the belly fat and taking steps to make yourself more attractive in general, etc.
Unless you have an abnormally small dick, which I'm sure most of you don't, it can go a long way in making the experience worth her while. Don't fool yourself into thinking that 8 inches is the average. And that's one of the very few attributes you can't change about yourself, so it's pointless fixating on that. 99% of the female population would prefer a man with a 6 inch dick who can fuck and is masculine and fit, instead of a 9 inch slob who cums after a couple of thrusts and then rolls onto his back like a dead whale.
