I see a lot from the DL perspective, so I guess I'll chime in from the AB end of the spectrum
While being an AB didn't inhibit my dating/relationship habits, I can say that being an AB did make me more selective with my relationships. I have only had a small number of girlfriends (3 in total) and I did have a Mommy friend for a time.
As being an AB is a part of me, yeah, I tried to be as up front as possible about diapers and regression in every relationship I had. My 1st GF was understanding and let me indulge in private, but wanted nothing to do with my AB side, which was fine, to each their own. My 2nd GF/Mommy actually engaged as a Mommy on a few occasions. My Mommy friend mommied me... obviously
My current GF/Mommy is the love of my life and she is very accepting, she loves all sides of me, Big Boy and Baby and she actually finds this side of myself to be both cute and charming
I can't say I ventured down any specific paths, I was just more selective with my partners and dating and as such, I made sure I had a good feel for who they were before I opened up to them. Some like my Mommy Friend and my current Mommy/GF approached me knowing full well about my AB side and out of curiosity surrounding the Mommy role. I also try to maintain a sense of balance in my relationships as well, for as much as I love regressing and being diapered and cared for, it's essential to do things as a regular couple as well, the best of both worlds
I can safely say that I am one of the lucky ones as well, my relationships have been incredibly fulfilling and the AB/Caregiver dynamic has come incredibly naturally in most
It is nice having someone who loves you for all of who you are, someone who genuinely understands and doesn't judge, that type of love and acceptance is incredible ☺
