The Megastore's sound system dragged my memory back 50 years.
The moment I heard that song again, I was instantly transported back to that magical summer of 1973.
David Bowie singing Time from his hit album Aladdin Sane produced an immediate, embarrassing and slightly discomforting rock hard, raging boner surrounding my crotch area, leaving my trousers somewhat misshapen..
What a trigger!
It felt like everybody was staring at my stiffy. As I stood in the queue at the checkout with the items I'd chosen for my evening meal. I attempted to strategically place my carrier bag to hide my embarrassment.
Once I'd finally managed to successfully negotiate my purchase and make my way outside, I uncomfortably hobbled to my car.
It was quite fortuitous that I had selected a nice dark, secluded area of the car park.
Furiously masturbating into a hastily snatched tissue from my glove compartment, I satisfied my sudden urge for relief.
All the while my mind re-lived the very real sensation that I had felt all those years ago - the first time somebody had had my cock in their mouth.
I sat there in my car -- now flaccid cock in hand -- and I was whisked back all those years ago to the weekend that awakened my first sexual experiences with another person.
It all tied in with the music of the time.
Bowie's Ziggy Stardust was the musical masterpiece of the moment and I was, and still am, a massive fan of all things glam rock.
It was not long since I had turned 18 years of age, and really was still just a confused teenager.
What I loved to do, or thought I was doing, was being outrageous and shocking everybody.
I would wear dark eye make-up. I was small enough at the time to fit easily into women's clothes. All my spare time was spent trawling thrift shops for retro garments.
Up until that point my raging hormones had only ever produced copious amount of semen through self-produced imaginings.
As I sat in my car that evening, which was quite warm for the time of year, memories of the events surrounding Bowie's visit to my hometown started to stiffen my prick once again.
Every male teenager who is negotiating and passing through puberty more or else follows the same pattern. We awaken every morning with an erection that is almost painful. A hopeful, erotically imagined scenario and a minute or two of vigorous pounding produces much stickiness and temporary relief.
That familiar process is practically the law. This daily ritual will I'm sure resonate with about 50% of readers, and greatly amuse the other roughly 50%.
I was an only child. A single product of an Irish, (lapsed) catholic, family, which at the time had caused questions to be asked and tongues to wag. This was not how Irish Catholics behaved!
