Orgasm?

Ok ladies.... seriously. I saved myself for marriage so obviously only been with one man. My husband is good at what he does trust me. Especially with that tongue of

His. But how do I know if I have orgasmed or not? Ladies at work say it’s like when you go to cloud 9, can’t take that feeling anymore, toe curling, mind blowing feeling. Almost like you have to pee but it feels so good. I honestly can’t say if I have or have not had that feeling. So I guess I need suggestions on how to get there, how to know I’m there or whatever.
