Hey guys! Sound familiar?

Any of you guys find your medications almost delete your sexual performance?  Your sex drive is still there and your desire to have it, but when it comes time to actually doing it, it's not what you're used to!  When I get an erection and my girlfriend gives me the go-ahead, I grab a condom, but when I try to put it on, it turns to mush.  My Neurologist says Lamictal and Tegretol are well known for that as their job is to calm everything down and keep it functioning normally.  When you get horny, the power of the drugs quickly kick in.  Anybody else have this problem?
