I'm no longer in any sort of a relationship whatsoever. Is it alright for me to watch again?

You just answered your own question and at least you are smart enough to see that it could become a problem. If you are watching it on a regular basis then you have a problem and not to many women are that understanding to have some pervert boyfriend getting off on more then them. See can be addictive like gambling and drugs are. Try weaning yourself off the stuff,then quit it alltogether, and if that does not work go to counseling for your problem. If you ever want a lasting relationship you have to stop the !!
