In Latin the gender of a word has little to do with actual gender or gender relativity. For example, the first word I learned in 9th grade Latin was nauta...sailor or mariner. It is a feminine noun despite the fact that few if any mariners were female.

If memory serves the word agricola (farmer) is the only masculine noun in the first declension.

[Verginius Rufus]

Actually, nauta is masculine, even though it is declined like a feminine noun. Likewise for agricola, "farmer." An adjective modifying either of those nouns would take masculine forms.
