Love the taste of my precum, too. Nice & sweet, little bit salty. I only produce a few ml on my own, but try to make most of it... Tasted my cum a few times (much nicer after a lot of fruit), but rarely swallowed. Always have good intentions to, but lose the urge after I cum. Held a load in my foreskin for 10 min or so once, it got a little more liquid & that actually tasted pretty good... It's also better tasting mixed with lady juices, going down afterwards.
When I'm with someone I'm really into, the precum just starts flowing, though - even when soft. So my underwear ends up pretty wet & silver inside. My partner loves the taste - & cos it just keeps oozing, there's plenty of lube...
