Dude, ditch that group of people. Your sense of worth shouldn’t be tied to your access to sex or how much sex you have. Oranguru is 100% right. Clinging to archaic views about sex and how it “affects” the value of a guy, gal, or nb pal will make you and those around you miserable. Those guys are no different, hence why they put you down to feel better about their own miserable existences.
