Long And Thin

Long ago in the mid seventies I sometimes went to an adult video theater and generally just watched hardcore porno and stoked myself off slowly edging for an hour or so.
I'd wear loose shorts and no underwear for easy access and a few times I'd let men who reached over to stroke me off. Had one old fellow say he wanted to lick me all over but he was way old and creepy so I refused.
Anyway this one time I was stroking slowly and a young guy me age reached back from the row in front of me and he gently stroked me for a few minutes and asked if I wanted to stroke him too. I got excited enough to go into his row and got down to see his dick and got a huge surprise. It was the biggest or anyway the longest dick I'd ever seen. At least 10 inches long but not very thick at all. It was almost funny looking but he wanted more than a stroke and he started to push my face down to his lap so I would suck him.
After awhile I was excited and throbbing myself and hoping he would cum when he said he wanted to "make you take my big dick in your hairy asshole."
I was afraid of getting a disease and wouldn't let him fuck me and instead when he said to meet him in the basement mens room for a good fucking I instead left the place but over the years I have wondered what that dick would have felt like.
I'm old and have a bit of ED but have been horny lately and thinking again about those days and imagine going to the theater and sucking some dick myself but the fear of disease still stops me.
