Hi guys, I read this manga not long before and I want to reread it. It's about this uke that often sleeps with men that confuse about their sex orientation and want to confirm whether they like woman or man, and he basically never sleeps with the same person twice. The seme is one of those, he was about 30, they sleep together a few times and become lovers later. And I remember they talk about "witch" which is a term refers to these people that are already in their 30 but have never done it before. So if anyone know what this manga name is plz let me know
