I cannot say that I have ever noticed the taste of another man's dick. Once I have started licking and kissing one, there is usually his precum mixed with my saliva as I begin sucking. This makes for a slightly sweeter taste as I progress, but do not receive any real taste until he cums in my mouth. For me, it is the whole sensation of having him in my mouth and the feeling I get as he swells up even more just as he releases his cum and I swallow it. Depending on his sensitivity, I try to keep his dick in my mouth using my lips and tongue to gently bring him down until he is soft. This allows me to savor the aftertaste of his cum a little longer.
