Ok ok, but like staying on the age regression thing, I don't really know much about it in itself, but this is what comes to mind with my limited psychology knowledge, but I do think it's understandable if he does have sex while sucking on his pacifier. When you are doing it for the very first time, with someone you do love, being all naked in front of that person you are at your most vulnerable, right? Again, I don't know much how age regression works this is simple speculation. It makes sense to me that rather than being just a kink or fetish, or just for the sake of it, it's the character being at his most vulnerable with the person he feels safe with and is able to use his coping mechanism while doing so, for me that clicks, idk y'all

While they have sex?!!???? Bruh
