I concur that there are certain pains that men have to face that no woman ever has to deal with.
As mentioned just now:
1. Splinters from wardrobes
2. Bruised egos from the knowledge that you've put together an Ikea sideboard "slightly wrong" (ie. so so wrong that you have to dismantle it, but wrong enough that every time you look at it, you're reminded of how much of a klutz you are.
3. Standing on an up-turned electric plug in your bare feet whilst doing routine household maintenance.
4. The horrific "p*bic hair/underwear band interface problem.
5. Nasal hair - or rather, their removal with tweezer beats any other hair removal pain known to man.
6. Anything involving our testes - punches, kicks...anything. This includes those 'playful' punches landed by children. LISTEN UP KIDS...IT STILL HURTS.
7. The psychological pain of watching our team lose.
8. The psychological fear of knowing that your twelve year old daughter will start dating boys in two years.
There are more that I could come up with, but I can't see my keyboard because I'm crying so much.
Kidding.
