I do not have a sex drive is this normal, should i be concerned?

What do you want?: You're a man in your 30's, correct? Maybe 1% of men don't think all that stuff is worth the trouble and aren't concerned. Right or not, there's no reason to worry. If your libido is gone and you very much want it back, you can almost certainly be helped. A thorough history and physical and some labs, including a check for prolactinoma and for hemochromatosis, is in your near future.
