I love being a woman, yes I have a monthly visit which is better than being distracted on a minute by minute basis by the thought of pussy you might get, want to get, and will never get unless you pay for it. Yes, child birth is painful as hell, but the end result was a lovely child, whom I will know 10 months longer than the father, because when I walked, they walked, and when I ate they ate, Let's not forget breast feeding, the ultimate bonding act between a mother and child.
Yes, the occasional gyno exam is necessary, but it is much better than bending over to cough and have your balls squeezed with and exploratory finger up the ass in the name of determining if you're going to get prostate cancer or not.
As to being past it after 40, guess again, men sexually peak at 17 and it is basically down hill from there. I can still have 5 orgasms a night, can you say the same?
As to bitchiness towards the same sex, well we have to have a tiny small flaw.
