How do I completely remove a wicked attribute?

[valdigthemlig]

My sim has gotten the "insatiably lustful"-trait, and while I do like how it makes the game harder, I dislike how it seems to make my sims crave new contacts which is an issue since my sim is in a committed relationship.

 

I've tried removing it through wicked attributes, and through regular cheats by right clicking my sim, but it seems like the trait disappears but instantly re-appears whenever I have sex the next time.

 

Is there any way to get rid of it completely?
