To be blunt, fuck those girls with their twisted ignorant abuse, and find a woman who doesn't have a little girl's mindset and agenda.
Women who put men down and demean their masculinity, propagating insecurities and false simlacrums of love, are worthless and most are irreconcilable in their venture into a solid, lasting relationship.
I'd say, fuck how big your balls are, do the testicle health routine, eat a shit load of celery, test out
Titan pills, and drink a ton of water, and don't ejaculate for like 4 days, then fuck the shit out of your "GF" and blast her with a giant load, and be like "see, big balls don't equal more cum, it depends on how sexy I find the woman, and just now I was thinking of my X-GF and that made me reallllllly orgasm hard". Then walk the fuck in the other direction.
