That shyt was high key inspirational breh
I played sports at a high level and I trained high level athletes professionally. Every body is different. Every person has a different set of physical skills that make them very effective if they develop and use them together. Find your strengths and embrace them. Don't try to be the next man. Be the best version of yourself. You gotta accept your weaknesses too. If you ain't tall you ain't tall, and that's life! I'll tell you a secret, most tall dudes aren't athletic at all. A lot of short people are athletic they just don't recognize or develop it.
My sex improved when I stopped trying to fukk like a porn star. My dikk is not big, I want it to be, hahaha, but it isn't. I had to accept that. I looked up positions that work well for dudes my size and I use them to my advantage. If a girl can make herself cum with a finger we can do it with our dikks, we just gotta figure out what spots to hit and what positions work best for us. I suggest increasing your core strength. Sex is reliant on those muscles. Thrusting power is all core muscles. Yoga's basic positions are sex positions. Practice yoga breh. Next girl you fukk with will be shocked at how strong and flexible you are while making love.
