A few years back I was at the beginning of my "bi curious" days and had only a few quick experiences with another unexperienced guy and we just jerked each other's cocks, but the thrill of being naked and performing a taboo act like that was extremely exciting as before that I had only fantasized about doing something bisexual, but that only lead to jerking myself off which I did enjoy greatly and had become quite skilled at.
One of the first indications of my interests began when I was working delivering food for an Italian restaurant and one of our regular customers named Richard who would order the same meal every Saturday night was an older gentleman who lived alone in a very nice home, but his voice had an obvious gay affect to it. Not long after I started delivering to him he would always keep me there for a while talking and asked questions about me and my life with a flirtatious way and would touch my shoulder and arm constantly during conversation and once quickly dropped his arm down and his hand brushed across my crotch as he smiled deviously.
During another usual Saturday evening delivery to his house I knocked on the door and instead of his usual grand vibrancy when he answered the door, he first only opened it very slightly to see who it was, then looked past me to see if anyone else was around, then finally smiled at me and said, "come on in Jeremy, let me go get your money". As the door swung open he spun around like a ballerina and started down the hall and I was instantly shocked when I realized that he was wearing a women's sheer negligee robe that barely covered his ass and through the transparent material I could that he was completely naked.
When the shock of this sight wore off I realized that it was exciting me and making me quickly horny. He was in the bedroom down the hall for what seemed like a long time but may not have been. When he finally emerged from the doorway I instantly saw that the front of the robe was open, and his large cock was fully erect. I stared at it as he approached me and took in the sight of the nice length and girth of his cock and noticed the fact that he obviously groomed his pubic hair into a short neatly trimmed square above his cock and his balls looked smooth also and were big and hanging low.
We had our usual conversation of small talk and as much as I later and still to this day wish this had a more erotic ending, unfortunately I did not have the nerve to grab his cock or do everything that I thought of during later masturbation sessions. I couldn't even bring myself to acknowledge or mention to him the fact that he was naked, wearing a see-through robe and had a massive erection. This I would regret forever as this opportunity never recurred because a job offer for the career that I had studied for in college took me away from my delivery job and any chance to have another encounter with Richard.
It took a couple years after that night for my curiosity to build to the point that I started to think of ways to finally act on these instincts. I knew of a small somewhat dirty and disgusting sex shop in town and after "chickening out" a few times I finally got the nerve to go inside and check it out. Inside the small store was filled from the floor to the ceiling with books, toys, DVD's, sexy underwear and costumes and any other erotic goods that existed. Some I had never seen before and some that I wasn't even sure what they did.
There were a few other men walking around and most were a bit older than me browsing the movies, magazines and toys, and they would occasionally look at me and smile although admittedly at this point of curious experience I had no idea what any of the smiles or signals meant or most importantly what was in store for me.
