Whenever I had sex with my GF, I cannot last long. Pump 5 min wanna unload lia.
And I wonder whats wrong with me.

But when I had my first FB, I could pump for 40 minutes and made her cum multiple times and yet I couldn't cum easily.

BTW, my FB is much prettier and more curvy..so nothing to do with look or body.

So I guess is the "fit". Your cock and her pussy fitting.

Try fucking other person and see whether same problem.
