Principles of life don't just apply to one person; they apply to all. So, what I'm saying applies to Cromartie as well as Zeke.
Second, you're focused on the issue of right/wrong. I'm focusing on the issues of dynamics and consequences. When you sleep with a woman for any reason, there is an expectation on both the woman's and the man's part. Hence the consequences of such an intimate relationship. I hear men say of women after having sex with them, "She's too clingy." Well, DUH!
That's a dynamic of intimacy, especially for a woman. She's likely to want
MORE regardless what she says.
And depending upon the woman, the woman's background, the woman's motives, the woman's education, the woman's esteem issues, etc., you get a wide range of reactions and consequences.
Oh, and for the record, finding the love of your life isn't a matter of marrying the woman who is best in bed. Surely, you don't believe THAT do you?
