My partner just kinda gnaws on my upper arm. Straight up asked her to stop early days of us dating and she said something along the lines of "but that's how I show I love you" and just kept at it.
10 plus years later it's a wonder my arms haven't callused over. Love that weirdo
LOL, yeah I was pretty surprised when I first started dating my wife and she reared her head back like that old cat video and then clamped her teeth down around my forearm. Now I like it.
