That intense feeling

I’ve never had an orgasm but I think I’ve come close? The guy I’m hooking up with was rubbing my clit and just the way he did felt so good but also felt really intense, so intense that I had to stop him. It reminds my feet being tickled, like I’m happy and giggling but also it is torturous to be tickled for so long. Lol idk if I’m explaining right. But I wonder if that intense feeling is what I’m supposed to feel on the way to an orgasm? I’m just so confused what the actual process for an orgasm is. I’m just wondering if I am getting close?

Also is it weird that it just felt too intense for me that I had to stop it from building up?
