How do you feel about a woman’s past?

Men over 30, how important is a woman's dating history to you? Let's say she's also over 30 for simplicity.
Would you consider each of the following as positive negative or not important?

1. She hasn't slept with anyone yet
2. She hasn't been in a long term relationship
3. She has been married before
4. She has never been in love
5. She has dated many men casually but none seriously

Any other factors about her past that you consider important?
