Bullsh1t lol. A girl will fvck you if you can get her friends on her side. Charisma--social influence, savviness--are R & S selected traits; it aids in the survival of her and any potential offspring & she wants her son to have those genes. I know plenty of guys that are low value and, physically at least, unattractive who kill it. They get by just on being friendly, non-needy, fun--the type of people you just want to be around. Everyone trusts them, so isolation is no biggie.
Approach a women in a group and see how far your high value, sex appeal, dominance gets you before her friends drag her off (even if she really, really wants to bone you on the spot). I say this as a guy who largely gets by on value--my results are best when I dial that back and work the friends in friendly, pretty boring convo so that they let me get with the girl I want.
