Organise my Porn

How should I organise my image collection? By model or by site or something else?
This is my dilemma as they both have advantages and disadvantages.

Option 1:  Collection\Images\Model\Site[Date] Set {1,2,3...}
Pro - Easy to find Model alphabetically
Con - Models on many sites create a lot of useless folder structure.

OR:

Option 2:  Collection\Images\Site\Model[Date] Set {1,2,3...}
Pro - Site rips can be kept together
Con - Model's sets are not kept together

OR:

Option 3:  Other – Please elaborate.

I must admit I am leaning towards Option 1 at the moment, but I still may be convinced of some other yet unthought-of arrangement.
Thank you.

Something like

Porn/age group

So you enter the porn folder, than you see 16-22, 23-28, 29-35, 36-40. Than, inside folders you see porn kinds. Bukakke, lesbian, gay, trio, orgy, SM, etc. Once you select the genre, it's like redhead/blonde/brown/bizzare colours.
