I disagree with most peoples views here; most members have more experience and knowledge than I do but I look at my DL/Little lifestyle as... wait for it.... a lifestyle .... it's not a sex fetish that I engage in a few days a week for a few minutes in my bedroom.
Every week there is someone new to ADISC seeking advice on how to come out; but tenured and new members here always say "why tell anyone" "diapers are a sex fetish keep it secret" "do you tell you mom what colour your underwear is?" etc...
CLEARLY AND EVIDENTLY ABDLs WANT TO COME OUT - ABDL is different than a sex fetish and there is a natural desire for many of us to want to let our friends and family know about our little side, it helps friends and family understand us and view us the way we want to be understood and viewed. It also opens the door for us to openly be who we are around them (wear a diaper, wear toddler'ish clothes, carry a pacifier...).
I love my lifestyle, I want to wear 24/7. It's more than just a diaper it's a lifestyle. Why is it a bad idea for me to tell my friends/family? Fear that a best friend will not accept it and will break off the friendship?
My only advice is... if you're new to ABDL and want to come out of the ABDL closet, then you should wait at least 4-6 months before you tell anyone, make sure ABDL is a long term thing for you before you tell anyone. You need time to understand, develop, and figure everything out for yourself before you can try to explain your lifestyle to someone else.
Now: If you're not ABDL and you do only use diapers in your bedroom for sexual activity then you should keep it to yourself you freak. (kidding).
