<3 cute boys.
I My Me! Strawberry Eggs is quite fun, for manga try Boku Girl.
True, I forgot that one, that is also a good one.
I My Me! Strawberry Eggs - About a male PE teacher that can't find a job but one school that needs a PE teacher hires only woman. So he decide to crossdress as a woman to get the job and he is fricking awesome at his job.
I consider it a crossdressing anime because he also does it in public. And yeah I know that most people are looking for light-hearted crossdressing/gender-bender anime but I would like to shine also attention on more serious anime in this genre. For if there are people interrested, now or in the future, they at least know it excist.
Just remembered another (sort of) crossdressing anime:
Mayo Chiki! - the main character isn't a crossdresser but one of the main-side characters is. She is a girl dressed as a male butler for reasons. When the main character discovers this he keeps it secret. As thanks for this she wants to help him get off his fear of woman.
