So here's the deal. I just read a post on TRP (https://www.reddit.com/r/TheRedPill/comments/5szls9/woman_has_a_threesome_with_her_beta_boyfriend_and/?ref=share&ref_source=link) and it got me curious. How do I know if I'm good at sex like women say I am? In the past few months I've banged 3 girls. First one told me how much I made her climax, the second one still hits me up, and the third one i apparently gave her her first orgasm. But is that really true? How do I know if I'm actually pleasing the girl?

EDIT: How do I know if I'm the "bull" or the beta?
