Advice please

So I’m 14 and I masturbate quite a bit but I can only reach an orgasm by vibration or water pressure. Anyway when I had sex for the first time a few days ago I couldn’t orgasm and idk if it’s because it was my first time and a bit painful, but also felt good, or because I am so used to masturbating and even though I’ve tried a lot of things it’s only those to things that make me finish. But anyway I was wondering why that might be? Do I do it to much? Is that gonna be the only way I finish? Is it my fault? And please don’t judge that I had sex. I was ready and happy with my decision and me and my bf are almost 15 (we used two forms of protection) Please only comment advice that I can use to help. If you don’t agree with this or you are going to comment something rude or judge mental please just skip past this.
