Had my first orgasm.. I think

My boyfriend and I are VERY sexually active and usually when we have sex it doesn't really feel like anything, but this one time I snuck him into my room (because I'm 17 and my mother would kill me 🙃) and we had sex and I don't know if he was hitting my G-spot or what but omg I started shaking and I clenched on to him and It was like a come to Jesus moment it was so good, but Idk why I don't get them anymore it was only once ☹️☹️,, comments? Concerns ? Feel free to put them, just don't be rude🙄🙄.. thanks 😁
