King of Prism by Pretty Rhythm

These are anime involving ice skating and are primarily popular with fans of Yaoi or Boys Love. King of Prism contrasts with Yuri on Ice primarily in the cheerfully colorful aesthetic and light-hearted feel with over-the-top comedic fanservice, whereas Yuri on Ice is much more dramatic and realistic as well as focused on professional figure skating and realistic relationships. Regardless of their differences, the boys of Yuri on Ice and King of Prism are definitely attractive and talented performance artists! Not to mention the music is awesome in either series. 

When it comes to Yaoi, BL, and Otome fanservice and comedy, Osomatsu-san and King of Prism will deliver it in such an over-the-top and hilarious way that you will be guaranteed to smile or laugh like crazy. Osomatsu-san's got scenes in some episodes of the series parodying the tropes and stereotypes common in Otome and Yaoi genres, whereas King of Prism does the same through the entire movie. 

There is so much over-the-top cheesy humor with fairly strong BL/Yaoi vibes present in King of Prism by Pretty Rhythm and Binan Koukou Chikyuu Bouei-bu LOVE!. No matter which one you enjoy, you would most likely enjoy the other just as much. These two series involve groups of good-looking young boys along with their friendships, hardships, and just having fun. They're light-hearted series which, even if you can't take them seriously, you may seriously grow to love them. Watching either with a friend is pretty much a guarantee that you'll have a fun time laughing together.
