No, it's not a Devious Devices blindfold or a graphics problem.  One of my many many mods makes my character experience visual distortions the more aroused they are. I don't know which one! I thought it was skooma whore with it's drug affects, but that wasn't it! Can someone please help me figure it out so I can turn off this visual effect!? Sometime I wanna play a horny character but I need them to be able to see and walk a straight line!
