I mean, you don't have to go full-blown fursuit and conventions if you don't want to. Most furries never actually bother with fursuiting--speaking from personal experience, it's hot as shit (especially outdoors or in summer), you can barely see or hear anything, and if you wear glasses they're prone to getting knocked off your nose or fogging up so badly that you can't see anything. Many fursonas exist exclusively in artwork or stories--either commissioned or self-drawn--and even that's optional.

You don't even have to actively participate in the community if you don't want to. Many furries are passive members who just follow artists, lurk in streams or group chats, occasionally leave a comment on a submission, and generally exist in furry spaces. Literally the only requirement to be a furry is to say you're a furry!
