I mean I don’t find that gross or anything I think it’s cool but couldn’t letting it “drink” your blood or whatever cause a lot of diseases/infections idk how big leech bites are but if you do this everyday it could probably cause scarring too. Actually what’s the life span of a leech? I’m sure there gotta be a better (even if harder) way to feed it. Besides are leeches even smart? like the leech might not even recognize you, I doubt it cares about you anything more than food. Idk that would just make me a bit sad.
