Yes, it's true. Men, not all of us, but a great deal are more parched for sex than women are...Some men will smash any p*ssy they can get their hands on, it doesn't matter if she's ugly, bad built, stink, etc. p*ssy is p*ssy to some dudes because they don't know when's the next time they'll ever have it again.
Men are not as disciplined; most women, for example, could go a year without sex and find other ways to pleasure themselves (sex toys, etc) and be fine with it. Men on the other hand, generally speaking, the average man doesn't want to spend a whole year beating his dikk (pause) if he can help it.
