It's a yagi or shounen-ai manga. Where there is a pair of roommates. One of them is constantly sneaking into the others bed. In the first chapter I believe that guy tells him if he keeps doing he might get mistaken for a woman. Also the reason they're roommates is because the first guy father insisted he look after his friends son. Sorry I can't be more descriptive.
