She has set the example for how I would likely approach this
I can not imagine my wife ever wanting to do this adult baby scene, but that is not the question we were asked to discuss.
To answer as directly as I can, if I came home to hear my wife confess that she likes to wear diapers and sometimes act like a baby, I would...
How would I feel? I would feel shocked at first because we have been married a long time and I am just now learning about this very important part of her make up. I would feel somewhat confused and maybe hurt that she waited until now to tell me about something so important to her. I would feel anger.
How might I react? I would keep my mouth shut and listen, for hours, days, weeks or as long as necessary to understand. I would only ask questions for clarification at first. I would want to fully understand why she likes this, what need is being met by doing this, and what she is seeking in dressing and acting like a baby. (i.e. does she want to be a baby all the time or just on occasion, does she want to wear diapers to bed? Is there an erotic component to this? etc. )
Would I truly be able to accept her? Oh yes, no question about accepting her. That is not even a passing thought. She has set the ultimate example for me to follow in that she totally accepts me with my strong need to look, feel, and act feminine on occasion. How could I possibly consider not giving her that same love and devotion in return. There is no reason other than adultry that I would ever not continue to love and accept her as she is, with or without her diapers.
Would Ithink it weird? Would it repulse me? Yes, I would think it was weird, initially. I thought it was weird when I read about it in this post. But on further examinination and after reading about AB, DL, and the various needs of people in to this scene, I would likely stop thinking that it is weird once I understook fully what is means to my wife.
The word "weird" is an unkind word for "can't relate" in my view. I just have difficulty thinking that anything that is part of my wife or anything that she needs can be weird. I have to much love and devotion for her to think that way. My goal would be to understand, to try to relate to her as much as possible, and give her the love, attention, and acceptance that she deserves from the one who loves and accepts her most....as she is...with her need for diapers and somethings to act like a baby.
