Please help! No one can answer my orgasm question

Okay I really really need some guidance.

I'm 20 started have sex about 6-7 months ago. It's been getting better as I finally got comfortable and I love my man very much, but I can't tell if I'm having an orgasm. When he gives me oral, I can definitely tell I'm having an orgasm. But when it comes to sex, I have this build on tension and then a release, but I don't have this "all over my body" feeling that people talk about. I don't squirt, I don't have my vision go blurry. I feel good after sex, but unless I get a clit orgasm, I walk away just feeling "okay."

The research I've done isn't helping because it says something like "if you have to ask you're not having an orgasm. You'll know for sure." I know that statistically some women don't have a g-spot or don't orgasm through penetrating sex or whatever, but I've noticed that those women say they feel NOTHING at all. I definitely feel something. I just don't want to be one of those girls who can't have mind blowing sex. So I guess my two questions are

Does it sound like I have orgasms during sex?

And what's some advice to have better orgasms?

PLEASE HELP AND THANK YOU
