This one is really good too:

http://www.mangago.me/read-manga/baraou_no_souretsu/ The protagonist is a hermaphrodite.
http://www.mangago.me/read-manga/hi_manyuaru_ren_ai/ The seme might be intergendered, but it's never made clear.
Anyone know a manga about people who are innergendered (I think that's the term.) call IS or Isay or something like that. thanks in advance
