Looking back on my first post, it was snarky, and I apologize for that. I made a snap judgment that wasn't fair to you. I'm sorry.
I guess in general I become nervous when we quantify what is "acceptable" in other people, because it can lead to objectifying people in a way that I don't think is true to our calling as Christians. Whether it's previous sex partners, or other previous sins, or even other non-sin characteristics (height, weight, etc.), by and large we are taught in society that a relationship is about us and what we want. I've seen this play out in the church as well, especially in the area of sexual past, but any time we create a "want list" for a future spouse that disqualifies people who do not fit.
Based on your response, it sounds like this isn't what you are doing, which is good, but I think it's so prevalent in our culture and indicates a self-centeredness which is common to all mankind that we must constantly engage and strive against it.
Does that make better sense?
