Joe?
Nope. 
At least 36 hours, but with many different people (and with the help of pharmaceuticals). I didn’t even notice how hungry I was till it was over.
I’d guess about 7 hours.
About 14 hours - but that included breaks for sleep. It was also made a little easier by the fact that there were three of us so people could bow out when they wanted a breather (or just to watch).
45 minutes of solid effort when I was 16… the last time I was ever in shape for that kind of stuff.
That excludes the half hour of oral beforehand.
Just to expand on that a little, it was about 7 hours on each of two consecutive nights (around 14 hours in total) with the same partner both nights. I was also staying at some of my parents friends house while attending a church teen retreat.
<checks watch> I’ll let you know when we’re done.
I’m taking my girlfriend to Mexico for a week, starting tomorrow. We are planning to set aside one day to do exactly this.
I’d say 3 or 4 hours.
If that’s you in the room next to mine, KEEP IT DOWN!!
Seven minutes. I think we would have hit the ten-minute mark if I’d held still.
One day but I didn’t time it, I went 8 times she went 14; I do remember the count.
April 28th, 1971, Farragut hotel, Knoxville, TN. A memory that will live forever.
I had a session once that lasted between seven and eight hours. Constant sexual touching throughout; when we weren’t fucking we were touching, licking, and such. It was definitely too much, and I was sre for days after, but at the time my libido just kept screaming “More, more!!” I will never do it again, but it’s a helluva great memory.
I was in a cubicle at work once for about 16 hours straight.
Somebody was getting screwed.
does that count ? 
I’ve been there.
I think I even saw the historical brass plaque thingy along side the road that commemorated the event!
I live in Knoxville. If the place is still standing, email me the room # and I’ll take a memorial photo for your collection.
A couple of times in the 45-60 minute range with the (psycho) ex-wife before she became upset and brought everything to a crying, bitter halt. That was just intercourse, because there was never anything else with her except excuses.
I’d give just about anything to have a woman who wanted and appreciated more, and was willing to be an equal partner in the process.
After about ten minutes, my elbow gets sore.
C’mon, somebody had to go there.
If you loosely define it, I once spent a day and a half in bed with someone (yes, we got up to go to the bathroom/for meals/etc. and slept, but we didn’t do anything non-essential except screw).
13 Years and counting
Oh you mean actually engaged in the actual act (nude, tab A into slot B action)? I don’t know, I never really kept track of that. Although a girlfriend and I way back in college managed to stay in bed for 24 hours straight (off and on copulation for a full day).
