    I wouldn’t have an issue with them sucking my blood in moderation, I have a lot of the stuff, sure, go ahead. But why do the bites need to itch afterwards? That’s a dick move and a bit counterproductive tbh

      The actual answer is that they have to inject some stuff that dilates the blood vessels and an anticoagulant so the blood doesn’t immediately self seal the wound as they suck it out. We react to that stuff and that’s why we itch.
