As the title suggests, I can't tell if I've had an orgasm before. I am 25F, sexually active, and sex feels great. Awesome. But I know for a fact I haven't orgasmed with a partner before. Eventually I'd like the get there, but first and foremost...

I can't tell if I experience an orgasm when I masturbate. I essentially push down on my pubic mound to very indirectly apply pressure to my clit, and do that while looking at sexy materials until i hit a warm wave, or peak I guess, and feel like stopping. There is a bit of that peak feeling, so it might be an orgasm, but if it is, it seems very weak (especially compared to how people describe orgasms). Does anybody understand the kind of sensation I'm referring to? Is this an orgasm? If it is, how do I have a stronger one? If it's not, how do i learn to orgasm?

Any input is appreciated! This is something that's been on my mind for years.
