My girlfriend (25F) has never experienced an orgasm. Not through masturbation or through sex.
She takes anti depressants now but even long before that it was still a problem. I'm not sure if they are actively contributing to it.
It's clear she would love to experience it, and there's nothing I would rather do than give her that pleasure.
She gets the most joy out of penetration. She likes me eating her out but I never get the same kind of enthusiasm as with actual sex or with me using my fingers.
We have thought about adding in a buttplug and adding a vibrator while I'm giving it my all.
Is there anything else I could do? Any suggestions from people who have been through the same thing?
