What is the real purpose of sex?

I want to have sex but I don't understand what is the real purpose of sex? I want to understand it completely on a deeper level. I'm a deep thinker.

My story: I'm a male 28 and I have a lot of problems. I suffer from depr., burnout, trauma, erectyle dysfunction, performance anxiet., etc. and I have too much stress in my life. I had a couple of bad sexual experiences and I'm sexual traumatized. I have anxiet. from having sex and I can't live like that anymore. I want to change it and unlock my full potential in life. I'm an introvert who lives isolated because of bad experiences with people. It's very hard for me to go outside and meet new people especially women. I grew up without a family and I don't have real friends so I don't have anybody to ask for help. Psychotherapy didn't helped me so I'm looking on the internet for the answers I need. I have a lot of questions about sex. Thank you for helping me!
