I’m not only rather new and rather inexperienced in the grand ANR scheme, but I’m also quite young too compared to most guys and gals in this scene. I don’t know if my word will hold any weight as a result, but I’d like to offer my two cents anyway. Anyone can feel free to correct me on anything.
I’m not sure there’s any real way of signalling one’s interest in ABF, short of wearing a heart-shaped badge with the letters ANR on your lapel. It’s still quite a niche interest today, and it’s hard to tell who practices it without talking about it because of its deeply personal and emotional component.
Heck, I still haven’t heard the terms ANR or ABF ever used in the wild or among any of my friends. I think part of that is because many of my friends are single and/or childless; they’ve not gone through breastfeeding in their lives and haven’t experienced the intimacy of it, and therefore have no context of it to want to introduce it into their lives. Perhaps this is why a large number of women in this community are mothers? (This whole paragraph is me talking out of my ass, so feel free to disregard it.)
On the point about sucking boobs and being a breast man, I’m not 100% sure they’re as clear a signal for liking ABF as you say. I’m *very* much a breast man and have a lean towards much bigger size. I also enjoy sucking boobs, in part because I’m a breast man. But the first time I partook in nursing, I realised that there is a VERY stark difference between titsucking and breastfeeding. Breastfeeding is such a deeply intimate activity, and the look/feel/whatever of my partner’s breasts themselves had little to do with that closeness. I could find that closeness with any woman of any boob size. I don’t think that’s something someone can fully grasp until they’ve gone through real nursing (at least, that’s how it was in my case). They can go hand-in-hand of course, and titsucking can very much be a gateway to nursing, but someone being interesting in titsucking doesn’t necessarily translate to being into ANR.
Sorry I went on a bit of a monologue, you didn’t ask for this 😅
