I think most guys want to taste their cum but chicken out at the last minute. (and won't admit they want to try it).
I had trouble like you at first but I forced myself to do it.
Now for the last few years I eat my cum every time I masturbate and I crave the taste. I will shoot directly into my mouth legs over my head or lick it from my hand or even cum on food.
I just can't get enough. I just wish I could share this with my conservative wife.
By the way I am straight and do not crave any one else's cum but mine.
