All I know is what me and my son has going on. He's 15, has had 2 girlfriends, been on dates with 4 girls, and isn't a virgin. I tell him to ask out the girls he likes and to not be afraid of rejection as it's a numbers game. He does and it works for him. He's also a big pc gamer and he has real friends he plays pc with and hangs out with. it's the same with his friends. Theyve all had girlfriends.
Maybe if this 66% thing is true, it means the boys/men willing to put in the work of talking to girls/women just have much better odds. I've been back in the game for about 6 months and I've asked out around 15 women, not using apps or going to bars. 4 successes. Not bad I think. Not being afraid of rejection is key. If you are afraid of that I'd assume it's easy to not try. These 66% just need to practice talking to women and it gets easier and easier
One of my women friends told me she likes when a guy shows interest and just asks her out, and this approach works pretty well. It's simple.
