Hey, I don't know how to change tags if anyone could show me/ change the tag "masturbation" to "fingering" because last I heard... it's not masturbation if someone else is doing it >_>

Not to be a pedant, but ... yes, yes it is. "Masturbation" applies to stimulation of the genitals by oneself, but also by another, as in "mutual masturbation."

Obviously, though, the tag is most useful if it is used to designate only those cases where it's stimulation by oneself and not by another. So, yeah, if it's someone else letting their fingers do the walking, the tag should be "fingering".
