Not ejaculating as much?
Men get that way as they age. They would squirt a lot in their teens and twenties, then after the mid-thirties it tapers off.
If you want to get your ejacuations stronger, longer, with more volume, then you'll have to get into the habit of exercising regularly, jog, diet and lose weight for at least a year without cheating or letting-up, do squats (one of the kegel exercises), practice stopping your urination in midstream just by thinking about it (another kegel), and most important, get your body hydrated, drink lots of water. Obesity lessens ejaculation, so does a lot of bike riding, unfortunately (that's because of the unsplit seats that traditional bicyclists would ride on that creates semi-impotency due to constant anatomical pressure on that area).
Here's a video on Xtube.com showing a vidclip of a guy shooting a LOT. It's called, "white rain is pouring down" You need to register yourself on their site to get a login (free subscription) in order to view it.
