Libido sups that do not backfire?

Hi there
Been away since years as I have mostly recovered. However, I am still susceptible to mini crashes. Some medications do that to me. But 99% of the time, no numbness.
I have been looking into ways to increase my libido. Circumstances require me to be ready. And VitD and C help a bit but not enough to keep up with a much younger woman.

Any supplements (e.g. horny goat weed, etc) that are known to at least not make things worse for us? Not cause a crash?

Thanks
