These are all of the Shounen-Ai tv series, or anime with very heavy homo-erotic themes. No OVA's are included, but miniseries are.
This list consumes of Yaoi and Shounen Ai anime. Some of them are not officially labeled either, but based on what happens in the series, I put them in this category.
Note: These are the worst among the shows I have completed; dropped anime don't count.
