Looking for a manga

[uran10]

I was reading this manga where the male protagonist's family ran a sex toy store or just an adult store, something like that and I believe the female protag asked him favours so she could somewhat explore the male body and satisfy her thirst for knowledge. The last thing I remember is the male protag being afraid when she was going to either see / touch his PP and him pushing her away because he was afraid. Anyone have any idea what Manga that was?
