Nope, not unethical. They are still your stories no matter what pen name you use. In your new profile, you might, though, note that you previously published here under the previous name. Than, if someone challenges you on stealing someone else's story (even though it's your own), you can point to the profile notation.

From 4-star 1 May 2011 review by Examiner.comís Acquanetta Ferguson of menage novella Dark Primeval
: There is also something to be said for a man who writes erotica. Some donít get it and write porn, but Habu gets what erotica is all about and the story comes off as a powerful read.

From the 4 1/2-Star August Rainbow Review on I Met a Man
: . . . a thoroughly wonderful reading experience for me. I look forward to reading more from the writing collaboration of habu and Sabb, who I believe make an important contribution to gay literature.
