I have recently found out/put together that my boyfriend is (forgive my lack of grasp on terminology) ABDL. He has dropped hints about it in the past -- wanting me to put him in goodnites, spank him like a toddler, etc. -- along with some more subtle cues, and I recently (accidentally!!) stumbled across an online profile of his where he said he was a AB/DL and wanted a mommy. After a lot of reading and digesting, I am totally supportive of him and want to embrace this as a part of our relationship and lifestyle, but other than the maybe once weekly comment, he hasn't said much. The past few times I have been with him I have been making an effort to baby him a little more and have been bringing up the possibility of putting him in goodnites, and he is responding really well. Last night I asked him if I was on target with what he liked, and he said I was, but kind of shut down after that. I told him that he could always be honest with me and I wasn't going to turn him away, and he told me that he has been and then changed the subject.
I am really worried that he feels he can't approach me about this because of my past -- I was open with him about a guy I dated who wanted to be my "daddy" and I was not into that at all, but I have discovered through him that I am much more attracted to the idea of playing the mommy role. I feel really bad for possibly making him feel like he couldn't approach me because of that, and I really want to make him feel embraced and cared for. I'm just confused as to what the best way to do this is -- I know that he is very sensitive and I don't want to hurt him further by thinking I know everything about what he likes when I probably only know a little. Obviously this is different for everyone, but how can I best help him know that I am more than okay with introducing this into our relationship if it's something he wants? I'm worried that if I'm too bold he will shut down, but if I'm too passive, he won't open up. I care about him a lot and want this to work, so any advice would be greatly appreciated.
