Numb penis

Hi, I took ashwagandha for 5 days, about a week ago. I stopped taking it because I noticed numbness and a significant decrease in libido and sexual sensations. It’s been about a week since I stopped, but I haven’t recovered yet, and I’m very stressed about it.
I’ve been taking Trintellix (vortioxetine) for 3 years without any sexual side effects.
Could the ashwagandha have caused this, and is it likely that I will recover soon?
