In my experience YES definitely. I have zero sex drive. I mean my sex drive was a little low a year ago, but I still was interested in sex at some level. Now I don't even get erections. I haven't ... you know... I'm alone... in months. I was thinking about going to my doctor and getting blood levels done. But i know it's the medication because there was a period of time, almost a week, where I wasn't taking my Suboxone and guess what came back? Yes sex drive.
