Hello. If your sex drive is low you need to have your testosterone levels checked. If they are low, you need to find out why and undergo testosterone replacement therapy. If you are urinating more frequently than usual, you need to have your urine checked for infection. If you have an infection in your prostate gland, for example, you may need several weeks of antibiotics to clear it.
Legally, I cannot prescribe medication over the internet. Beside, you need to know what you are treating first. You need to get blood and urine tests done, then you will know what medication is needed.
