So like pretty much every other guy alive, I jerk off at least once a day. I'm not a huge gusher but I usually cum a pretty standard amount. Then about a week ago (after not masterbating for a few days) I jacked off as normal and only about 1/3 of the amount of cum shot. It's been like that for the last 4 days! What's going on. I'm 29 and nothing like this has ever happened before. Anyone got any ideas?
