If you fucked for 5.5 hours ed meds probably won't be of any help to you. What will help is to be physically fit to the extent where your resting heart rate is optimal for your age and level of conditioning.
After fucking for 5.5 hours you were probably just exhausted.

I notice that the right woman and positions will give you the stamina.
My record this year was 3 pops in 36 minutes (I booked for 1 hour, and just couldn't believe I popped 3X and still had 24 minutes left).  I could have gone to a 4th pop and was still hard, but I was a bit embarrassed that I'm working my ATF too much for only 1 hour, so I just talked to her the remainder of the time.  I tell you that I could have stayed another few hours with her and pop some more.  Maybe it's a combination of your energy that day; rest; and chemistry.

LOL,


I couldn't believe I had it in me either.  This was a very unique experience with someone who wasn't exactly a professional.  Just two friends with lots of benefits both ways!  

It wasn't a continuous erection.  We had long breaks of resting and talking, then we'd get all hot and bothered and start up again.  She teased me on the 4th try that she wanted a "full man" not a "half a man", so my ego couldn't let me stay droopy!  She wasn't really serious, but I'm still not one to disappoint.

We've discussed future meetings with more warning, as this was actually spur of the moment.  She's even threatened to bring a friend!  With this in mind, I want to be fully prepared.
