@SoloSera I feel like you're projecting a bit, as you're the one seemingly unable to understand simple concepts.
You claimed that him likening virginity to purity is "gross", and that he probably thinks women's hymens are a good indicator of their virginity. You thus implied that he considers virginity to be a physical trait, as you apparently do, hence your dislike of the word "purity" based on your notions on the matter - that however is clearly wrong, since in the context purity referred to the virginity of a man, and so must necessarily be unrelated to pure physicality.
