My first true sexual experience was when I was about 15 with a guy 20+ years older than me. He took me out on a few dates to some nice restaurants and treated me really well. He went down on me once, got me off, and opened my eyes to masturbation (I had literally never done it before then but I'm grateful every day that he enlightened me when he did). It was obviously all kinds of wrong and I knew it back then but didn't care, and I harbor no ill feelings about it. Sometimes I google his name to see if anything pops up.
