It's never seemed more to me than 1) a man gets access to more pussy than he'd have taking his fat, balding ass to singles bars every night; and 2) a woman using her twat to get a better lifestyle than she'd have staying an old maid with a cube job.
They think it's going to be an equal partnership but it ends up one person doing all the work (usually the woman). Then there's the lying, cheating. Possibly abuse. The nasty relatives...
You're chained to the same sexual partner supposedly til death, no matter if they're no longer attractive to you "in that way"- or vice versa (most other mammals mate, part and the female raises the young on her own).
Then there's the 50% chance you'll just get divorced anyway.
And kids? More tears shed over them than good times.
I just don't get it, but... good luck.
