I a world where the wildest conspiracy theories and openly talking about killing political opponents are considered sfw but a topless woman is not, I couldn't care less.
Seriously: I can never tell if a woman is just friendly or interested in more. You have to be blunt. I probably missed quite a few potential relationships due to women dropping only subtle hints and me never getting them. My gf made her intentions clear from the start and not only was this her only chance, it's also very attractive to me.
