This is a great question! I don't like how pink my lips are, but I'd never thought to wonder whether it's affected by hormones! On the bright side, in general full, rosy lips are considered an attractive trait in men as well as women. (How many romances and gay erotica novels are filled with descriptions of lucious lips on men?). I think it is one of the traits that makes some people say things like "why are trans men all so attractive?" Well, we're not, but many of us possess traits that are technically feminine but are also seen as attractive (and very rare) in men such as full lips and large eyes and a tendency toward the much sought after in gay circles "bubble butt." Sure, we would rather fit in to a more normal male mold, but if you can't fix it then embrace it, right? I just like to think of myself as having super attractive lips, unlike many unfortunate guys. 😉
