Most of the time I can't have a sissygasm without some stimulation of my dick. One exception was the first time I used a dildo attached to a reciprocating saw (with a fucksaw adapter). It should have been used with a router speed controller. My reciprocal saw only had two speeds and both were too fast to use safely with the fucksaw dildo. Needless to say, my curiosity and impatience got the best of me. It was an insane experience, literally drilling me, and the noise was loud and scary! I came fast and hard without touching my dick. I was shocked by how hard I came! I was a little sore afterwards, but, no harm done. Unfortunately, I have not been able to use this 'toy' much because of how loud it is. The other time I came from prostrate stimulation alone was when I was riding a big and hard dildo and I was moving around to experiment with different angles. There was one strange angle that hit the spot just right. It was like discovering my p-spot! I rode it hard and deep hitting the magic spot, and I had the second best orgasm of my life without touching my dick. But, I have only been able to cum this way a few times. It helps to dress like a sissy - tight little dress, bra, panties, thigh high shiny stockings and high heels - and tell myself that only a sissy slut can cum like this, i.e., completely ignoring her worthless little dick.
