Haven't been myself

Very recently ive noticed that women have been boring me very easily. I only call when its convenient for me, if we are more than friends they are primarily on my mind for like a week or two then it's back to normal. I don't know if it's the situations that make me feel this way, or if im just not too easily amused, either way it's left me in a bind. I haven't had sex, kissed, gave or received head since *December 20th* and it only bothers me when im horny. I just havent been myself lately :/
