How can I restore my libido that was almost entirely diminished by my medications without changing my meds

I'm 18f and due to my poor mental health I'm on 3 different medications and they made it so that I'm never turned on no matter what my girlfriend does to me. The things that would make me horny just do nothing now and it's causing a rift between my gf and I.

I cant mess with my meds since it wasn't easy to find something that helps me so I'm looking for ways to help my situation without messing with my medications.
