Here's two quotes.
"A man has both a penis and a brain, but only enough blood to use one at a time."
"It's the story of life. Boy meets girl, boy gets stupid, boy and girl live stupidly ever after."
Now, I'm not fond of the first because it's cis-centric. That is to say, not all men have a penis. The second one is misogynistic in its implication that girl is already stupid. So they aren't the greatest quotes in the world, but they point to something that I agree with. Love/lust turns people into morons. I read a few medical blogs, and the one thing they all have in common is at least one story about a guy who went into the ER with a story like "My girlfriend had never been with a guy who wasn't circumsized, and there was a steak knife..." And now everyone cringes. It also seems to lower inhibitions. People in love do some seriously embarrassing stuff that they wouldn't dream of if they were in their right minds. They permanently alter their body with tattoos with their partner's name. And then they break up. And now they can only ever date people with that name ever again.
I am an aromantic asexual. I have never in my life felt erotic love (platonic, yes. familial, yes.) I go through life being astonished by the shockingly bad decisions people make while under the influence of that stupidest part of the brain. But sometimes, I think it must be nice to be able to feel emotion so strong it shuts down everything else. To trust another person so much that you'll allow yourself to be lured into extremely compromising positions that will then require the swift use of shitty excuses when you get caught by a parent coming home early or a child who couldn't sleep. Then I realize that I don't even feel love, and it's still trying to con me into being a moron. A powerful force indeed.
