An orgasm is about moving, breathing and having consistent stimulation on or around your clitoris under your control.

It will take time and practice to learn another masturbation technique.

All anti depressants interfere with sexual functioning, especially orgasm.

There isn't a "spot" in your vagina that will bring you to orgasm. Your clitoral system is complex. It's about clitoral stimulation with vaginal penetration.

I urge you to consider making some dietary changes and gradually coming off the meds.
