I'm sorry you feel conflicted over sex. IMHO, addiction is, in itself, a demon. It dictates when you'll take time out of your day to get your next fix of whatever it is you're addicted to. Regardless of how important the task your doing is. You're just consumed with the next time you'll get to have that oh so lovely fix. You'll lose focus, lose a grasp on reality, and you're only really meaning in life is that next fix.

It doesn't matter what your addiction is, alcohol, sex, cigarettes, it's always going to get to the point where you don't care what happens to both yourself or anyone else, as long as you get that next fix. So, yeah. Addiction, in and of itself, is one whopper of a demon.

Now, I'm not saying this demon has any religious connotation attached to it, I'm referring to it as more so an inner demon, a living breathing monster that lives inside you. Maybe that's what you're experiencing with your alcoholism. Drinking copious amounts of alcohol is also known to be a huge buzzkill when trying to get off. It causes men to have trouble with getting and maintaining erections, and limits a woman's chances of arousing to the point of climax. Not only that, but it dehydrates both sexes so they can't produce near enough liquid, either lubrications for the female and seminal fluid in the male, and failure rates are high.

Did I also mention it tend to make people black or pass out, sometimes before they can get into the act? What's the point in having sex, if you pass out before you even start? Or how about not even remembering it? Sure, complete black outs are rare, but they happen more frequently with alcoholics than casual drinkers.

So, all in all, I think alcohol may play a huge part in that break down you had at your friend's place, and why you are having these "demonic" visions whilst dreaming. It's your subconscious telling you your alcoholism is becoming a demonic presence inside you, consuming you, and that enough is enough.

Have you been to therapy? Do you have a therapist? If so, have you discussed these with them? If you don't have a therapist, maybe you should think about finding one. I know it's helped me when I was in dire straights.

Good luck and remember, sex isn't the enemy, it's actually very natural and very common. Every adult I know of masturbates. I don't know if you're an addict of sex, per say, as everyone has that desire to satiate that need to orgasm. However, it's when it becomes all consuming and you don't do anything else but think about that next fix, and have fixes multiple times a day, then maybe it's time to consult a therapist on how to get better and resume a normal healthy life sans the addiction.
