I mean.. It doesn’t take that much brainpower to understand such a simple concept, but I’ll break it down for you.
I’m sure you enjoy/prefer sex without a condom, right? Now imagine you’re having sex with 7-10 girls a day. Some come in squeaky clean, super respectful of your boundaries, and most importantly, you feel comfortable with them. Some come in dressed like a bum, disregard your preferences, smell like shit, and make you feel like your skin is crawling. Are you going to have bb sex with all of them? No. You will probably choose the cleaner girls who you trust more/get along with and have seen a few times. That’s called being selective
If you wouldn’t have raw sex with ALL of them, but would with SOME of them, then you’re picking and choosing, the same as most of these girls do. Hope that helps you understand better.
