There is a saying, "sin fascinates before it assassinates". If sin had no appeal, man would never have fallen, and the few of us who needed the cross would have little trouble honoring it. But sin does have an appeal. Indeed, most sin is much like the immoral woman described in Proverbs.
I'm not entirely sure if Solomon sought to personify all sin as an "immoral woman". It's possible he was speaking quite literally and just wanted to protect the reader from adultery and prostitution. But I've always taken the interpretation that he did intend the "immoral woman" to personify sin, just as wisdom is personified as a great woman.
For most men, few things are more appealing than an attractive woman. There's a saying in marketing: "sex sells". If you want someone to buy something, make it seem sexy. Put a scantily clad woman on a billboard, you're at least going to turn a head, and likely sell your product.
Satan is not stupid. He's spent the last 6,000 years tripping the human race up over its own shoelaces. Sin, much like a woman, is enticing. But the immoral woman in Proverbs has no interest in fulfilling her promises. In chapter 7 verse 23, we see that following such a woman lead one young man into a trap: He was shot in the liver with an arrow, and did not survive the encounter.
Sin may seem enticing. Indeed, every single one of us has felt its pull, and until the day the Lord calls us home and clothes us in glory, none of us will be truly pure. For the rest of our lives, every single one of us will be fascinated by all kinds of sins. But we don't need to follow our noses to that particular pie. James tells us to submit to God, and resist the devil, and he will flee from us (James 4:7). Where is the logic in letting him win? Resist!
