I’m just taking a guess here, but I’d say that’s part Adult Nursing Relationship and part Erotic Lactation. I really am not sure, though! LOL. There are so many nuances, and ultimately, I don’t think it really matters that much. I think Infantilism is when there is physical, emotional, and behavioral role playing going on, and sometimes even props involved. But there is some overlap with all of these as I am seeing more and more.
In any case…I totally get it, as you can tell. LOL. I find the whole lactating thing incredibly hot. I wish I had experienced that, but it’s also pretty hot when you’re not lactating! Either way! :)
