Orgasm advice needed! Please read!

First off, I’m technically a virgin as far as penetrative sex with a live penis, but I do masterbate with my fingers. Like I rub the clit and I use a vibrator thing, but I don’t put it in. I only use the vibrator on my clit. I like to rub the vibrator up and down and Sometimes I shake and have the chills and my body clenches up for only a few seconds though, I don’t know if that is considered an orgasm. If it’s not how can I orgasm? And please don’t suggest fingering dildo inside me because it hurts too much and I have tried putting lube but it still hurts, I also have tried the shower head thing, also doesn’t work. I practically tried everything to have an orgasm it just doesn’t happen! I have never actually had an orgasm and I really want one, I do Watch porn and it get me horny and want to have sex and have an orgasm but I can’t! Please give advice on how to have an orgasm! I’m desperate! 😩😩🍆🍌
