i started to cum regulary rather late, when i was 16 or so. even now, at 19, i don't cum that much unless i don't cum for 2 days or so. my cum is not thick and white , it's more transparent with hints of whitish and sometimes it contain small silicone-like lumps of something (sperm, i guess). as i sad, unless i keep of cuming for at least 2 days, my cum doesn't shoot in strong and healthy streams (like the ones seen on porn movies) but it sprays around in a 2-3 series of a few beads, and it almost doesn't have any distance. worst of all, if i cum more than. let's say, 3 times a day, sometimes i don't even produce any sperm after orgasm. i thnik my balls are somewhat smaller than average, considering the "above average" size of my penis. is this normal or what?
