Hi, I am a Leo-Cancer cuspian. This is known as the Cusp of Oscillation. Essentially, my star sign means I'm destined to be bipolar.
I suspect my POIS is related to my starsign. There I said it. Now everyone laugh. I am extremely moody, manic, or depressed, or I oscillate between these states, and this oscillation is amplified when I ejaculate/orgasm/almost-orgasm.
