Why are men the authors of their own sad lives? Go and impregnate young girls and not marry them and look for other young girls wen they older?

Like,all the 'hot' girls either got kids, impregnated or just fat these days. And then they end up alone sleeping with prostitutes or HIV positive girls cause nobody will have them? Some use their hands which is just as pathetic. Why can't they grow up and realize they need to treat everyone with respect, it's pathetic asking the girl out that you used to tease cause all the others got kids or just bagage and the young ones get to be picky. I'm not even young but I'm out of the dating scene gracefully. Must be worse for the older ones who still want to date, or the lonely older guys. Karma turns right around and bites you, be carefull how you treat people.
