It's a humorous reply, but it's not very elegant.
And no, it's not suitable for a man, as it wouldn't even rhyme. But culturally, at least in Mexico, men are not supposed to praise their own looks. (That's assumed as a female characteristic.)
A man who would like to use an unserious reply might say "¿Cómo me ves?" and make a gesture of "admire me".
Perhaps he can say something like "Yo, como los buenos vinos (mejorando con los años)".
Also, among men it's common to answer to "¿cómo estás?": "(Pues) aquí, como el tío Lolo (haciéndome el tonto solo)."
"Tonto" can be substituted for a bad word, but not necessarily.
I'll ask around for more alternatives... one can always count on creativity.
