ejaculatory dribble

Long ago, I could ejaculate several feet. And when I was finished, I could just wipe the tip of my dick and put it away.

Some years back, my ejaculation volume declined noticeably. Specifically, I will now ejaculate 50-75% of ‘normal’, and the rest will drool out over the next ten or fifteen minutes. This has been a hassle; a quick wank turned into a lengthy milking and cleaning session, and usually a shower.

Is there an exercise or technique to alleviate this, or is it something I might need a doctor to deal with?
