How can i undersatand

hi im married, how I can understand that my wife get orgasm without asking her

wait are you asking how will you know him she has one with out asking her?

There is no way to tell really. Most women fake it sooner or later, for different reasons, and men have no idea (remember When Harry Met Sally? haha). You can ask around the question like ask her what else she would like you to do, or how. When given such an opportunity, she'll probably tell you what she wants (and thus, indirectly, what you've probably been doing wrong or not enough of). Use those tips for a better job next time and maybe she'll get a real orgasm. Or, ask her if you can watch her masturbate, and observe how she does it and what she likes, then do it on her like that.
