You never said if your manhood stood for 1.5hr or it kept going
soft....and you have to work it back into shape!!
If you are on high alert for 1.5hrs, then all i can say is, it's
to do with your state of mind...sexual intercourse is different
from diy. When your muscle works and acid seeping in, it may take
the erotic-ness away and cause you to 'lose that loving feeling' to
cum. You will have to focus on the mind, the pleasure, and ignore
the muscles, the angles, the stretchings, and contortions!
If you are a victim of fluctuating 'tides' to your didi, then
you may have to consult a urologist for some presriptions.
