There is a lot of variation in the male sexual response, and I thought I was somewhat of a freak when I was younger.
In a "contest" of sorts, when I was a teen, a group of guys had a contest to see who could have the most "O"s in an 8 hour period. (Just some stupid thing kids would think up). I hadn't really discussed any of this with anyone , so I didn't know what the norm was.
In 8 hrs. I had 19 (nineteen). Naturally everyone thought I was lying, and I found that the norm was in the single digits, much to my surprise.
I talked to my dad, who also had the same "gift", as he put it, so it must be something genetic, and nervous system related.
In any event, in my 30's in a very short but fiery relationship I once again "tested the waters", and had 13 in one afternoon. (which amazed me considering my age). Now at 44 yrs old with a little more maturity and a stable relationship, I've learned that QUALITY is way more important that quantity. Make fewer count more, and the satisfaction derived from those is much more "complete". So 2-3 is just fine with me these days. (Besides I get enough of an aerobic workout at the gym
