That is the question. Probably the most mentioned (by young men & boys) sexual practice. Slice and dice it for the benefit of the SF community. See if you can answer the who, what, when, where and how. I started this... so, here goes. I was introduced to 69 when I was 15 YO, by an older girl, actually a woman, of 18 YO. Some of the girls in the orphanage had told her about my sexual activity with them. Let's call the older girl "J". While kidding around with me one day, she enticed me into planning a sexual tryst with her. I ended up in her room one night, after midnight. (Only the oldest girls had rooms to themselves.) After a few preliminaries, she got her mouth around my dick and was sucking it. I honestly didn't know what this was all about. Eventually she said, "now you do me". Seeing me hesitate, she said, I'll show you how. With her whispered guidance, I got into it willingly. She moved on. Stopping me, she changed ends with her head between my knees, and proceded to giving me my first real blowjob. At the same time, she guided my head down between my thighs, into my first 69 experience. Of course, I was a willing student. Since then, I have enjoyed the practice up to a point. My enthusiasm varied depending on her participation and enthusiasm. As I grew older, I changed my preferences to pleasuring each other, one after the other. I find what's going on on one end, distracts from what I should be focused on on the other. And vice versa. 69, to me, isn't as great as it's cracked up to be. And so it is and will be. Over to you.
