That is huge, i never did more than 5 hours (i think is the record), but 4 years ago was usual for me continue to opem cam sites (every 30 minutes) and watch girls for hours or have the smartphone ( i don't have it anymore) for 6-7 hours while using pc.
the question is how long did the erection last ? 2 hours seems impossible ? or did it get hard then soft, rest a little then hard again ?
