Tips for having sex pain free



i’m 19 years old and i’m practically still a virgin. i had sex once but it was barely sex only the tip really went in but i really want to have sex but my body just won’t relax and i get too in my head about it all, even with just fingers it absolutely kills. so i was wondering if anyone had any tips for how i can relax my body and make sex less painful. i have tried lube but it still really hurts.
