I had kidney stones in january. ever since i have had a lack in sex drive and have been for the most part impotent. are these issues related?

No: They are not related. See a urologist for evaluation of erectile dysfunction.

Indirectly, maybe: The timing suggests a connection, as your asking implies. Could the stones have physically affected your function in some way? It's unlikely, but physical problems ought always be ruled out first. However, one ought never underestimate the psychological effect of illnesses. If you check out fine, consider asking your md for a referral to someone who can help you sort out your personal reactions.
