I find that I'm curious about tasting my cum while I'm jerkin it, but once I finally do cum, I'm not interested anymore.
Although, I'm a huge precummer and cummer. So I really like the taste of my precum, it's slightly salty and a little sweet. When it oozes down my shaft, sometimes I'll lick off a big drop off my finger. There's so much of it, might as well taste it if I'm not using it as lube. There are other times where I can stop right before I'm about to cum (edging), and my dick will ooze out some cum but will stay hard. When that happens, I let run down my hand, and I lick it off. My cum is also slightly salty and a little sweet, with a slightly bitter aftertaste. Actually doesn't taste like much, which makes sense, since there is so much of it and it's pretty watery.
There was one time where my cum rag slipped, and since I'm a powerful cummer, I got it in my mouth, eyes, and all over the wall. It tasted alright, burned the fuck out of my eyes (ouch!), and made a huge mess that got everywhere. I simultaneously learned that I don't like the taste of my own cum after an orgasm AND that it needs to never go in my eyes ever again.
