I agree with Athena,
for me..it depends on the girl, my horny level, alcohol level and then...most importantly, how horny is the girl.
I'm 30 but given the right partner...my first shot can tahan for about 30-45min of non-stop bonking and BBBJ. Of coz the girl is at the receiving end of all the fun lah. Second shot, thrid shot...also almost about 30-45min.
With one of my horniest FB in recent months, we bonked for about 3hrs non-stop. She was probably cumming non stop, and I cum 4 times I think.
With a not-so-horny girl...1 time or 2 times in 90min. but that's boring.
