No its not normal. I'm a one pop guy. But I could probably manage 2 or 3 in a session if it I haven't got laid for yonks.
In my 20's wouldn't take much to make me cum, but with in 10 mins, I was hard once more, and ready for action
In my 30's, I learned to slow things down and not to rush, and when I felt my self cuming, how to delay
In my 40's, could easily go for 3-5 min, before cuming, and round 2, would have to wait 30 mins or more
Now in my 50's, sex maybe 2-3 time inn the year, don't aim for sex, now into foreplay, and playing games
