From finding my dad's porn I realised I was interested in both sexes, but as the vast majority of people know it's far easier to see your own sex naked than the opposite if you want it to be in real life. The male changing room at the local swimming pool was open plan, nudity was the norm whilst changing, and to be honest I learnt how to masturbate properly by watching guys in the showers. I also discovered that I loved the graffiti in the public toilets, be it tales of single men just wanting relief or men saying their wives wanted to be involved. Most weekends I would be up and out early, there were two sets of well used toilets I could visit on my way to the pool, and then another three at least on the way back. The first was a very old building, two cubicles and a urinal, behind what was now a garage but used to be a theatre, aptly known as "the Queens", always porn fastened to the back of the doors which had holes in, better on a weekday afternoon but still people visiting at 7pm on a Saturday often. My normal routine was to go in as if I needed a pee, if it was empty check out new graffiti in the left one but I preferred the right one, bigger hole in the door and more light through the frosted barred window. I would drop my trousers and underpants, roll up my tshirt, tuck my cock inside the toilet bowl if anyone was in until they made the first move when I would expose myself and start to masturbate. If it was quiet, just me and another guy (sometimes if there were others who could keep a look out) I would unlock the door, stand almost naked in the frame, and let them get a good look. This was the first place I ever allowed a guy to touch me, the feel of another hand on my cock had me almost immediately orgasming, and where I first brought a guy off, his cum coating my belly and hard prick. It was also the place I met the guy who introduced me to giving head, he told me he had porn and lived a few doors away, I was obviously very horny that morning as I would never normally have gone to anyone's house, but I followed him, he went into his back yard and then the house. Almost as soon as I was in he had dropped his trousers, nice length, big balls, decent bush. He asked me to get naked, which I did as he rubbed himself, then got some porn out. It was straight forward hetero porn, like my dad's, but wheras dad's had just been couples fucking his had them giving each other oral, and whilst I'd read graffiti about giving head before I'd never really understood it. Now I was looking at women with their tongue licking the slit, then cocks vanishing into her mouth. He asked me if I had ever done that, I said no, he asked me to. I was on my knees within seconds, his cock had precum glistening on the tip, and it tasted so good. I took it in, it wasn't a long cock but quite thick, and his moans told me I was doing well. His hands came down behind my head, he told me to keep still, and he began to fuck my mouth. It seemed like minutes but was probably seconds before I felt him buck and squirt, I swallowed as much as I could, he pulled back and his last spasm caught me on my face. He pulled me up, kissed me, licked his cum off, told me I was a good lad and to dress and go. I immediately went back to the toilets..... I will write more....
