At this point in my life, one-night stands are a distant memory. But when I was still in my late teens and early twenties I did it alot. Looking back on it now I guess I was a bit shady in my ways. After meeting a girl and flirting back and forth, as it went to the next level, I would say that I shouldn't because I was engaged, and if it did happen that it couldn't go any farther than that one night. Surprisingly, many girls were totally cool with this, and we would proceed with both of us knowing that it was just a one-night thing. After the night was over, when or if I ever saw the girl again somewhere, we would shoot knowing glances at each other, and maybe a smile or sometimes we'd even talk. And if someone else was around the talk between us would be totally innocent and casual.
It was crazy, but it seemed like when a girl went in knowing that it was just a one night fling, they would totally lose all inhibitions. Women really do have a "wild side". Unlike dating for awhile then sex happens and the girl acts all self-conscious and does stuff like not yet wanting you to see her naked, or like wrapping a blanket around herself when she walks off to the bathroom and things like that.
But I consider myself EXTREMELY fortunate that I still have my health and that I made it through those days without so much as a pimple on my manhood. Its not even close to being worth it to run around like that again, especially this day and age. I don't care how much protection is available. I played russian roulette too many times and I'm done while I'm still ahead. Meaningless one night stands lose their excitement over time.
