I've never in my life achieved orgasm without stimulation from a vibrator. It's not an actual vibrator, it's supposed to be a massager for sore muscles, but I use it for external self pleasuring, meaning I only use it on my clit. At first it was overwhelming but now I'm completely used to the feeling. I know a lot of people use pillow, fingers, table edges and even showerheads, but I've either never found them stimulating or found them a bit painful (showerhead) I want to try new methods because what's wrong with switching it up? But I just can't try. It's just not stimulating enough. Sometimes I think maybe I'm too used to the vibrator, which I probably am, but also even before I learnt how to masturbate I could never orgasm through other means (even inserting anything has low effect)
For context I don't have lube, I use coconut oil which I only apply on my clit, so it's safe to use.
