I am curious about the dynamic that results from your wearing your diapers in bed that you share with your spouse or partner.
Does s/he know?
If no, why not? Do you not mention it? Does s/he not notice?
If yes, how does s/he react? Does s/he make comments? Does s/he touch your diapered bottom?
When you get up in the morning, do you change your diaper in front of him/her? If yes, what is his/her reaction?
Here is the situation in my house: she doesn't usually notice and I don't bring it up intentionally. In the morning I go to a different bathroom. There are infrequent situations where I undress in the same bathroom with her and she sees my diaper, but doesn't usually react to them. There's also the occasional situation where we get "in the mood" after we go to bed and I take my clothes and logically my diaper off before we get more intimate. Sometimes I have to go take a shower because I am wet.
