Oh yes, I certainly agree with your previous contributor James (Oct 20th) erections are not always necessary.
I started my life long wanking experience at age four when, idly rubbing my totally flacid penis from outside my thin shorts, I suddenly experienced for the first time that oh so beautiful feeling. Instinctively I knew that I had to make this happen again and again but that I had to do it privately. So I continued in this way until at age seven some older boys took me in hand (pun intended) and taught me how to make myself hard and get a grip. The resulting orgasm was no more or no less exciting but it did arrive a lot quicker and certainly a lot more often. Years later I started on medication for a blood pressure condition, the dreaded beta blockers, which now only allow half an erection at best. Nowadays I start my stroking in this condition, the old excitement is still there and remains until orgasm, even though, in the meantime, I have gone completely soft. I hope to be able to continue in this way for many years yet, sex is not only for the young and virile!
