Sex with a girl is f*cking impossible.

I'm a 37 year old male, I believe i am good looking - five foot six, 94 kilograms, blue collar. I have been rejected countless times by girls for not having a ''big enough d*ck''. I have been cursed at birth and i blame my f*cking parents for this.

I had a few tries on Tinder, eventually after a few rejections I felt like i found a nice enough girl that made me believe my size wouldn't matter - turns out it always does. She was dropping heavy hints at having a type of carelessness in such insignificant things. We booked a hotel and met up. When we met up she was acting awkward, as if we never interacted before. I felt as though she was uncomfortable because i do look older than my tinder profile because i used pictures of my younger self, however i don't see a problem with that. This made the intimate experience awkward and we both were unable to really *do* anything. She gets up and interrupts the experience, i felt somewhat of a relief but then she proceeds to tell me that I'm ''not what she's looking for'' and she ''would not be able to sexually desire me'' or something along those lines while staring at my ...anyway i've been overthinking ever since and my ego has deflated massively, i don't know how to mentally come back from this and i'm scared i'm going to become someone i don't like. Please someone tell me what to do i've had enough.

What am I genuinely doing wrong?
