Hi,
Digital footprint-wise I'd say grab a throw-away or secondary email for everything AB/Babyfur related (Google accounts even offer a Google Voice number that you can forward to your main number should any sites/applications ask for it). This would suffice in separating your real-life matters from your little side (barring Google, ISPs and/or the FBI have an interest in you, then you have problems outside the scope of this forum).
To get your foot in the door, you used to be able to go to a few forum sites specifically for the babyfur community, the one that comes to mind is FoxTalesTimes, though unfortunately that forum is now mostly used for Babyfur/AB RPG game development, so not much social interaction going on there.
Furaffinity and Sofurry (not sure about the latter, since I haven't been on in a while) have a much larger active babyfur footprint than what you might find on here. Though even then, since both sites are more of a submissions based site rather than a forum/social media site, your exposure there might be limited.
From those sites you also might be able to find some communities that are based in IM programs like Telegram, Discord, Skype and much less commonly IRC (I think I even saw one on slack a while back lol). It just seems that what used to be all forum based is now moving towards IM based social media, so you might find the best luck with this approach.
Though nothing beats furcons I hear, I'm dying to go to one in person!
As for roleplaying, the IM option is where you'll see most of it happening, since it's much more accommodating of private conversations.
As always, I'm open to making new friends and am always happy to help, so if there's any concerns please ask away! (The babyfur side of the forum seems pretty quiet, so I doubt anyone minds!)
