In Act III, Scene 2 of Shakespeare's play "Romeo and Juliet," Juliet speaks these lines to express her frustration with the fact that although she has married Romeo, she has not yet consummated their marriage. The metaphor of buying a mansion of love is used to show that she has entered into a union with Romeo, but she has not yet been able to fully enjoy it. The phrase "though I am sold" suggests that Juliet has given herself to Romeo completely, but they have not yet been able to consummate their love due to external circumstances.
This passage reveals the intensity of Juliet's desire for Romeo and the frustration she feels at being unable to be with him physically. It also highlights the pressure and expectations placed on young women in the Elizabethan era to marry and consummate their marriages quickly. Juliet's words reveal her longing for physical intimacy with Romeo, which is a natural and human desire, yet one that is heavily regulated by social conventions.
Overall, Juliet's statement reflects the conflicting emotions that she experiences as a young woman in love, and highlights the complexities of love and marriage in the societal context of Shakespeare's time.
