so ive been thinking about this and let me tell you why. 

so when you steal stuff in the towns, you get used as a "public toilet" , but more like a whore, maybe someone needs to take a piss in the middle of the night (and some of people are into golden shower) 

also another thing, since scentless only works (or it worked) based on your strenght stat, why not make it when you get used by a werewolf or a huntresses cat to get marked by them while youre trying to recover your thoughts and energy to get up. 

in the next encounter with them or lupa, they would take a different approach (start off horny and ready to breed and that stuff) 

this way, scentless skill would be more of use then now making you as it says, scentless, or less, and you could fully clean yourself at the healing ponds and at the island and bathrooms
