Rabbit licking furniture, why? Unneutered behavior?

[Remy The Rabbit]

Recently, I caught Remy licking the ottoman and couch, and even my shirt. I don't know what he's doing, but is it maybe because he is unneutered? I really want to get him fixed, I even asked my parents yesterday (again) I can afford the surgey, but with everything going on I can't get it done right now. I know it's also really rare, but I worry about him dying during the process, though I still will get him fixed, just for the benefits.

My bunnies still lick my clothes, bed and my blankets. For them it’s just grooming behavior and I take it that they like me, all those stuff have my scent on them. Both my bunnies are neutered. Sometimes excessive licking can be because your bunny miss something in their nutrients but it’s rarely that.

My rabbit licks the floor and carpet. She also licks me to give kisses. Licking is a form of grooming so I’ve always taken it as a positive thing.
