The ones I have chosen to retain in my memory bank were positive experiences at the time and did no long term harm, fortunately.  If you are single, considerate and its consensual, then its one of the great fruits of your youth.  If you believe it is the pinacle of human emotional experience, then I feel sorry for you.

Maybe it might feel good at the time but you run the risk of getting STD's and aids. You also run the risk of it being the girl/boyfriend of someone you know plus inside of you, without you even knowing it, you will feel empty and dirty. Sex is only good when we do it the way our Creator created it to be, that's in marriage with a person you love, and they love you.

I do not think it's morally wrong,as long as neither person is being decieved.However,it's not for me.I've had them,and must say that I much prefer a long-term,monogamous relationship.Sex is something that gets even better the longer and better you know each other,and the deeper your emotional and spiritual connection is.

In my bachelor days it was more about the thrill of the hunt than the end result that made it fun. Nevertheless, there was nothing like a quick roll in the hay with ol' what's her face to add some lightness in your step. Just remember...you wouldn't want to jump out of an airplane without your parachute so don't jump in the sack without your protection.

Extremely positive. . .me and the wife do talk about past experiences both positive and negative and enjoy reminiscing (and exploring) each other's past experiences. . .One-nighters should not be the complete diet- but it can be a rare event that can be a positive memory for both people involved. . .people complaining about one-nighters remind me of people caught for speeding. . .don't wanna whine? Don't partake in the event. . .

Always remember the iron law, never sleep with anyone crazier than yourself!

Never done it, but from what I've seen the one-timers can give you some scarring expiriences, like diseases or a chance encounter with a "lady-boy."

Oh, I could never do this.

I have had many more than anyone should have I admit. In my younger days, I was very much a "cassanova" and think it was probably because I was compensating for my lack of direction in other walks of my life. Happens to a lot of young men. I still remember very well the empty feelings I had after most of them. I also remember denying them because I was young and thought that was what I was supposed to feel good about..conqering ladies and all. It was relly the chase that was fun, not the end result. While one or two led to a relationship of somekind overall, looking back, this is not a good thing, but know that its part of life as a young man.
