I hate having a small dick. I can be rich. I can be ripped. I could even be a little taller (dead average height). It wouldn't matter.
When I have sex with a woman, she will know that that's not all sex can be. Some other man can be all those things that I am with a bigger dick and satisfy her in ways I could never (assuming she hasn't already experienced that). She'll melt in pleasure instead of simply thinking it feels good.
Every amateur porn couple I see where the woman isn't obviously faking it, dudes with small to average dicks get a few moans and whatnot from the woman, while amateur couples where the dude is hung has the woman absolutely losing her fucking mind, gripping the sheets, shaking, etc.
"Get good at eating her out" is cope and everyone knows it. The physical pleasure aspect is a big part of it, but women want to be dominated and filled up. They respect you less for having to resort to oral sex instead of being able to get them to orgasm with your dick. They can love you and think your average dick feels good, but they will never be lustfully attracted to you for the rest of your lives unless you have a big dick that can make her literally short circuit.
