What is the difference between MF and FM tags?

[AsmodeuS10]

Is it ok if I just add MF and FM to any animation that has either one tag already?

They both exist because people sometimes write the tag the other way around, and adding both means they can be searched for regardless of which way each individual decides to write it.

 

Assuming you're referring to animations for SexLab, SexLab orders animation positions with female actors defined first, so the tag "FM" or "FMM" matches up with that and is used. But, "typical porn" tags usually do "MF" or "MMF". So both ways are used and accepted.

 

The framework will also automatically add the gender tags based on the position genders set in the animation registry. So if you add only one or the other, or neither, it'll still end up with both MF and FM ordered tags.
