Waking up in gay clubs

I really need some help. I have been going to bed with my girlfriend and about once a week I find myself coming to, I am always in gay clubs and a few times I have come to I find I am being banged in my bum by a huge gay bikie. I have no idea how I get to these places or no memorie of what has happened. I beleive somehow I am possesed by a gay demon. I definetly consider myself straight and feel quite violated and wrong when I come to and find several men degrading my mouth and my anus. Has anyone everheard of this type of possesion? Is this normal?
