I tried lexapro again last spring and it actually made sex painful. I quit taking it for that reason. I was wild in my 20s while self medicating. The mania would make me bad, and the substance abuse would make me worst. But I really blame my promiscuity on BPD and lack of impulse control. I'm (somewhat) sober now and rapid cycling and my mania makes me dysphoric so it doesn't really make my sex drive out of control like I believe my BPD did.
