Does anyone know the title to this yaoi manga? 6m1h2d

A couple has been going out for a while, and is living together, but the uke locks his bedroom door and refuses all physical advances beyond kissing, specifically anything involving him removing clothes, leaving the seme to wonder if he is no longer on love with him. He follows the uke to the library and thinks he might have been in love with the librarian. When confronted, the uke reveals that he didn't want the seme to be disgusted with his male body and was discussing with the librarian (who had undergone sex change surgery) about becoming female to better appeal to the seme. Then the seme tries to convince him that he still gets aroused by his male body by, of course, having sex with him 😉

I aslo the uke was always gay and the seme used to be straight, which is why the uke had no confidence in his s xual appeal

Looks like I never added this to my list, but I'm pretty sure that one of the guys were younger and a student, waiting for his graduation for their relationship to progress. I'm leaving another clue here.
