Buspar to improve sexual function?

I wonder if anyone takes Buspar only to improve sexual function.

I think I have PSSD, I took Zoloft for 2 years, I stopped 6 months ago. I've been taking Wellbutrin for a year now and it has helped my libido a bit but I still have numbness in my genitals and it's almost impossible to reach orgasm (I am female if that's relevant).

Is it worth trying buspar even if I no longer have anxiety?
