Bad boys are definitely my preference. It is funny because people will see me and a "bad boy" and afterwards be like, "hmm, y'all are an odd couple," or, "he doesn't seem like your type." Well I just love a man who could care less whether or not he is sexy.
Furthermore, ambition does it for me! And in this day and age, ambition and entreprenurial spirit can be showcased whether or not is is the "conventional" (read: legit) way!
Actually, I rather prefer the unconventional way because, in my opinion, that shows innovation. I don't know, just my skewed way of thinking, lol.
I also agree with the part about being spontaneous. I am an EXTREMELY spontaneous person, and most things I just do on a whim. I love a man that can keep me surprised.
