Yes, I was able to do it later in life and have fucked all night without cumming and even when cumming it would be hard and I could continue at will. I also practiced fucking without squirting cum and still had the sensations of cumming. In that latter method, I could go long periods without squirting. If I cum once or twice during the night, my penis would get very sore, but if I held back the cum squirts, my penis never hurt.
In earlier years, I could cum three or four times and be hard immediately without any noticeable wait to get hard again.
