Just in time for your next pub quiz night I came across this curious list of odd sexual facts. Amongst the gems are:

80% of men living in the USA have been circumcised.
Which I find at best sad but not surprising.

During sexual intercourse, in addition to the genitals and breasts, the inner nose also swells.
Weird! But why?

A teaspoon of semen contains approximately 5 calories.
So it ain’t going to do too much damage to your diet!

During an average man’s lifetime, he will ejaculate approximately 17 litres of semen.
Good grief, that’s almost two buckets! Although at an average 5ml a pop it is only one ejaculation a week between the ages of 16 and 81. Are you really getting enough?! Especially knowing that …

It’s possible to relieve depression through masturbation.
Now that sounds like the best excuse ever for a bit of Onanism!
