You probably guessed it -- rose's femininity is the womanly femininity of Romantic.
Some florals have added masculine elements: for example, carnation has an element of spiciness that brings in some Dramatic, and geranium has a bit of a lemony element that brings in cheerful Gamine.
Rose is interesting in that it has an added powdery and refined element that brings in Classic. So rose, as a note, combines passion and sexuality with restraint and sophistication.
If you're a Romantic Classic, this is a definitive fragrance note for you.! If you're not, a lot of rose in a fragrance may add more sexiness or conservatism than you feel comfortable with.
