I'm Still A Little Sometimes

So I've always had a thing for being treated like a little kid. Even when my friends were experimenting with drugs and girls back in high school, all I wanted was to curl up on the couch under a blanket while someone took care of me. Now I'm twenty-four and still into it, but mostly just alone or maybe with one other person at most. I started seeing this guy a few months ago. He's older - thirty-two. We had some really fun phone sex stuff where he would talk to me like the kid he always wanted as his son. It was amazing, I loved feeling cared for and protected in that way. Last week we met up at my apartment. When I opened the door, there he was holding a coloring book and crayons. He called me sweetie and baby right away. I felt all tingly inside. We did some naughty roleplay, but afterwards it just wasn't enough for me - I wanted him to keep treating me like his little boy. He understood and we went back to being daddy and my little guy. That was the best night of my life. But here's where it gets weird. He left early this morning, and now I'm sitting alone on my couch in nothing but a onesie he let me borrow. I'm feeling all soft and cuddly inside and can't wait to hear his voice or see him again soon. But at the same time, part of me feels ashamed about being so childish sometimes. Why am I still like this? It's not just about sex - it's comfort and love too. Do I have a problem? Or am I finding my real self through these roles with another adult who understands me?
