Second thought.
Whenever you see somewhat primative movies, or even westerns for that matter, the sex is rough and rugged. Much of the reading I have done on primative tribes NOW in existence also point to the fact of somewhat rough sex.
To a degree, we had little knowledge of sexuality, so few people ever even thought about "slow", love making sex. That was more an act foisted upon people by TV, magazines, day-time-soaps, etc. Nice sex doesn't necessarily mean that's the only way. In a sense, since it is portrayed more in public, it has demonstrated "THAT is the way to have sex" and made alot of guys think it's not good to be rough.
Yet, most girls I meet enjoy sex with men for that reason.
