@IronKratos It's all good. Just remember to check the wiki if you're unsure about a tag https://ehwiki.org/wiki/Main_Page Some tags have a "male", "female" and "mixed" namespace. Mixed is for activities between male and female characters.
Some tags can be confusing for example the ones pertaining to animals. Certain ones go by the gender of the animals itself whereas others go by the gender of the character being fucked by said animal. For example, for insects it's the gender of the person being fucked by the insect rather than the gender of the insect. https://ehwiki.org/wiki/insect
I have no idea why it's like that. I'm not a moderator, I don't make the rules. I'm just a guy who goes around tagging stuff to help people find what they like.
