This is the truth.Well, women are competitive with each other, same as men. Men are far worse though.
Young or old, men tend to hate any man who is successful with women. Instinctively. In fact, our entire male leadership have deployed active c0ck blocking measures by writing insane Laws around consent, marriage, gender etc. all to c0ckblock you.
Quick anecdote/humble brag.
Im 39, and plated a 19 year old a couple of months ago.
Went to grab pizza with her. Another I would say maybe 18-20 year old guy said under his breath, dude she's like half your age. (I actually never heard it, because my hearing is indeed poor on account of my age!). She later told me about it. I said I really don't care. She said she didn't either.
Truthfully, I want to high five guys that 'appear' to be dating much younger or out of their league. It inspires me to be honest!
