I don't know if this is normal

Hey guys. I am really questioning what is wrong with myself. Okay so I found out I like to do this ever since I was young, not knowing it led to orgasms. The only full way I can orgasm is to rub on the edge of a chair or corner/ having my hand in-between my thighs and rubbing them together. Now that I am older, and having a small sex life..(no penetration just oral) I literally cannot orgasm. I believe what I have is syntribation too. When my partner rubs my clit, I only manage to squirt many times, and I am not really sure what comes after that. I prefer my own method, but I don't see people talk about this at all, only just the common methods. I know everyone is different but I'm not sure, and I would love to hear what you guys have to say. Thanks.
