Defining "grossest or most unusual sex act" is subjective, so I can only give my personal opinion. To me, the most grossest or unusual sex act is fetish or role-playing where one or both partners involve defecating or urinating during sex.

I would have to say that the most gross or unusual sex act would be "forced ingesting" or being made to swallow a partner's semen, feces, or urine. This is not only disgusting in the physical sense, but can be seen as a violation of a person's body.  Furthermore, if someone is not comfortable with this then it can be seen as a form of non-consensual BDSM.
