Given it's a half-remembered article I read probably in Portuguese (and my Portuguese isn't the best), I strongly suspect your recollection is more accurate than mine here :)
No you don't. I was only catcalled for the first time at age 30, and it still sucked. It's not about beauty, it's about power. Now if only it were actually the power to attract cats...
Yeah, no, you don't. The times I've been catcalled it was degrading and gross. ("Hey, bitch, get back here and suck my dick" is not flattering. Also, I am fat and middle-aged, and the times I've been catcalled I was wearing sweats and a winter coat. It has nothing to do with looks, and everything to do with reminding you that, to some men, you are not a human being.)
