I've discussed the sexuality subject before under slightly different circumstances... that time I asked a Protestant message board (who I am friendly with, they understood it wasn't an attack) why exactly women should wear make up. In that case, as in this case (with "looking sexy") my intention isn't to confirm a set rule or principle, as though I would insist that all women should look like they're amish or puritan or something like that. Like when I asked about make-up, all I want to know here to is: why? Saying "it's ok to look sexy" and "those who don't think it's ok misunderstand" is an answer to a question, but not the question that was asked (I assume it was not an intentional side-step
). Again, the question is, why? What is to be gained? Even apart from the moral aspect of the subject, it certainly seems both easier and cheaper to dress modestly than it does to appear "sexy". So, again, why do it?
Let's assume that it's ok to dress in such a way thatyou "look sexy". Okay then, why do you want to? Some valid answers might be "to attract men," "to impress my boss," "to turn my husband on," etc. A valid answer is not restating your premise with different language. So, conceding for the sake of argument that it's ok to "dress sexy," can someone tell me why you would want to do that, and what benefit it is, as opposed to dressing and looking modest?
