How can women reach orgasm quickly during masturbation?

Patient's question:

Due to many factors or causes, I have been masturbating for many years, always using the method of crossing my legs and rubbing. Recently, I've noticed that I reach climax very quickly (perhaps in about 1 minute), which makes me a bit worried. I'm afraid that when I get married and have sex with my husband for the first time, I won't be able to handle it. Could you please tell me if my concerns are unnecessary? Thank you.

Doctor's answer:

Hello
Your situation is mainly about masturbation.
Advice: This concern is unnecessary. Please don't worry. As long as you control your emotions and move gently, you will also have a longer time and reach pleasure.
Doctor's inquiry: Hello, is there anything else you don't understand?
