"I no longer feel the desire for sex. I don’t know if its the pain medications or menopause from my hysterectomy "
I don’t think that it matters what strain. You should think first about what type of THC tolerance do you have? Then, do you prefer Indica (sleepy, body high) or Sativa (more uplifting energetic high). For sexual desire, you definately want to have some THC involved. Your tolerance can vary widely so I would start with a minimal amount first and moderate from there. Try a Kiva espresso bean with 5mg of THC and see how that works for you.
