Hahaha the cope in this thread is real, I pity older generations of men still believing in romantic ideals of years long gone. Ati marry a virgin and you won't have these problems. Once you pop her cherry she's going to wonder what other men are like and contrary to popular belief you can miss what you don't know.
As misogynistic and hedonistic as redpillers are they get it right when it comes to sex and relationships. You don't walk with your woman's vagina in your pocket, she could have been Mother Superior at the convent but if she wants to screw other guys she will and there's absolutely nothing you can do about it. You can treat her like a queen until she worships you or you can beat her like a dog until she wets herself at the sound of your footsteps but if she wants to screw other men she will.
Either you marry knowing infidelity is a very real possibility, hope that it will never happen and if it does you'll never know about it, or you avoid marriage altogether. There is no middle ground on this one.
