why is it that i seem to go through phases? one week i will be sooo horny to the point were it literally sometimes interferes with activities. i will be so horny that i am constantly thinking about sex, getting rock hard erections, needing to jack, fuck, watch porn, all of the above. then again, sometimes for days at a time i will not be nearly as horny. its like i can watch porn but not jack off. or not be as driven to have sex, be naked, etc. its kind of like a cyclical effect. any theories, thoughts?
