Italian is not only a romantic language but also a 'sexy' one. Having the closest dialect to Latin also makes this language interesting and romantic. It truly is beautiful, not too hard to learn, and can help you pick up other romantic languages, such as French and Spanish.
Oh, come on! French and Spanish sound great, but Italian is on another level entirely. Just listening to two people converse in Italian about any subject, even without understanding a single word, is pleasing enough to make it your hobby.
