In general the "healthier" you diet is the better/less offensive your cum will taste. Pineapples will make it taste a good bit better.

One thing I'll mention is medications, a lot of them probably have an effect. I'm a bodybuilder on a cut right now, been taking DNP - it tastes awful anyway and it makes cum and pre taste of it too.

but I know once when I was sucking a guy, his pre cum tasted so salty... I have tasted mine a couple of times and it had no taste at all...

In terms of smell, I guess may be I was eating meat that time and my dick smelled really good...(good to me, I don't know if some one else would like that smell)... because I had not washed it for couple of days...

Personal experiences about my cum taste, the more I eats fruits and vegetables, the cum more juicy and taste light salty sweet. On the other hand, if I eats more meat, fish and eggs, mostly the cum is thick and clod, also the smell is stronger. The taste is a little bitter, much heavier and complicated (its hard to determined).

Suggestion, try not to masturbate for a week or at least 4 days, then try your cum. It taste better and sweet and the smell is really good.

WoW! Your experience about taste of semen is amazing.
I always want to try my own like in the video but after cumming, I always feel… a little hard to put it in my mouth. Maybe I am not an actor after all.
