Other reasons to justify having a paci? I need your advice

So I told my gf of 3.5 years that I age regress and sent her a couple links explaining little space as well. I don’t know if she’s read them yet but she seemed.. accepting and like it wasn’t an issue.. but I don’t know that she really gets it yet. I’m gonna take it slow.

But I really want a paci again. I used to be in a ddlg relationship years ago but it was a bad experience and after that I swore I would never let myself regress again. But here I am a few years later regressing. I really… really want a little for big paci again. It was perfect as an oral sensory thing, better than chews. I want to get one but hiding it from her would be hard. I’m afraid she’ll think I’m weird… so does anyone have extra ideas of explanations for why a paci is important to you and what you would say if someone questioned it?
