assisted undressing -> assisted exposure
This may be an alias, however the description on Derpi implies only for use non-consensually, so if it’s the same here, maybe could just have the latter imply the former
This isn’t strictly speaking wrong, but love heart isn’t nearly as intuitive as Derpi’s use of floating heart, imo should switch to that.
Multi penis also uses multi, but you are correct. The reverse alias would also be fine, though may need to update the description of multiple nipples. Regardless, right now about 2/3 of relevant images are tagged with multi breast, and the other 1/3 are tagged with multiple breasts.
