There isn't anything wrong with aggressive sex, but I can give you about 5 that make ass to mouth wrong.

I don't think A2M is "wrong" in the moral sense of that word. It may be a risky activity in terms of health impact, but it's not morally wrong if consensual. Plus, it's not nearly as risky as most people imagine. You are already colonized with your own intestinal bacteria (duh) most of them are harmless anyway. It's only risky if it's from another person with a communicable, dangerous illness (like hep for e.g.) or if you have some kind of unusual lower G.I. infection.
