Brief Answer:
By arousing her properly before inserting

Detailed Answer:
Hello,
Thanks for using 'Ask A Doctor' service.

I read your query and understand your concerns.

Although there is no direct method to cause early orgasm for females but you can achieve it by investing more time for foreplay.

By doing so, there is a good chance that she will be aroused to the highest level which will cause an orgasm to come relatively early for her.

I hope this helps you.
Feel free to write back to me if you have more questions.

Thanks and regards.
