How to simulate the clit manually during sex like a vibrator does?

The vibrator I always put on high setting sometimes I do the pulse vibrations to get myself in the mood and edge a bit then I do full on and have an intense orgasm.
Yes I have been using my vibrator while having sex, but I want my husband to play with it until I orgasm.

Usually, he rubs it and it feels good, but i don’t orgasm I’m not sure how he should do it to simulate a vibrator….penetration alone doesn’t really do it for me so I want him to simulate me so I eventually don’t need the vibrator and can just orgasm with him alone

Should he use a specific finger or fingers or rub a specific part or do specific motions? How can he mimic the vibrations?
