No intercourse for over 6 months! No cum since Jun

I haven't had sexual intercourse for over 6 months now! The intense, unrelenting sexual frustration is causing the most incredible horniness!!! For a tiny bit of "relief," I started edging in June, always STOPPING just shy of ejaculation. I haven't actually cum since June 15! How much longer can I can stand this? No intercourse, no ejaculation, just repeated edging--always abruptly stopping shy of any orgasm. I'm FULLY ERECT most of the time, and it takes forever for my massive hardon to go down. In fact, the last fews days I seem to be always semi-hard.
