Oh my god, it deserves quoting:
"Your man today
But let's bring it up to date. What about your man today?
Well, it should be the case that recent centuries of civilisation have had an effect on him ? so that he does not try to impregnate every nice-looking woman he meets.
Nonetheless, the following are fairly safe assumptions:
your man is very keen on sex.
he thinks about it a lot ? much more often than you do!
however romantic and gentle he may be, deep down one of his major objectives in life is to get his penis inside you.
and once it's in there, he has a deep, driving 'biological imperative' to reach a climax - and pump his sperm into you.
Oral and rectal sex
So ingrained is this instinct to impregnate a woman that many men appear keen to accept any available female orifice ? even if it?s not the vagina. That?s why a very high proportion of men desire oral sex and a substantial minority (and it does still appear to be a minority) are keen on anal sex.
Conclusion
So, the average male is more interested in sex than the average female and is much more likely to:
feel very strong urges to have intercourse
take sexual risks, regardless of the consequences
be unfaithful
try 'commercial' (ie paid for) sex.
The slightest thing can set a man off ? for instance:
the sight of a woman's cleavage
a well-shaped bottom
a good pair of legs
even a whiff of perfume.
So, female readers, never underestimate the power of a man's sexual response.
You have been warned!"
I like the idea that the urge to reproduce is so strong that a man will stick his penis into a woman's bum or mouth. Not very clever are they, according to this article.
