Vaseline is probably the first lube guys ever used for jerking off as well. Whether someone told you about using it for jerking, or you found out on your own, it does seem to be THE lube. I remember when I hit puberty and was soon stroking off like a maniac but without lube, and soon my dick got sore. Just out of necessity I put some of Nivea lotion my mother kept in the bathroom on it to soothe the skin, and I accidentally discovered how incredible it felt to apply lotion and very quickly I got rock hard and of course had to jerk off again. After that I began using the Nivea lotion daily, but it dried out too fast, so out of necessity I tried Vaseline petroleum jelly and BINGO I hit the jackpot!!! I knew I’d end up using all of the jar and my parents would question me about it, so I walked to the CVS and bought my own small jar of it. The cute college age guy who was the cashier gave me a big smile and I felt like he knew what I was buying it for, which was extremely embarrassing. It didn’t take me long to figure out that Vaseline was also perfect to put on the objects I used up my hole. I would take one of the hammers from my fathers workshop in the basement, grease the handle with Vaseline, and ride it in my room (usually all night) while I jerked off. I had no idea what a prostate was at that age, but it was obvious that having something up my ass got me extra hard and gave me even more extreme orgasms than just jerking off. It was also around this time (middle school) that I began to hear other guys my age talking about Vaseline, usually joking about it, and I knew that what I’d found out on my own was actually very popular. I was also into hiking in the woods or mountains by myself and I soon began taking a small jar of Vaseline with me so I could jerk off in nature.
