That was never the question in fact I honestly never hear men question anyone's womanhood. We accept you as is
Men look for certain qualities in a woman and that can be different depending on each man. I think there are some basics that they want/expect when considering a woman to wife up. We all know that there are women that men are just going to have sex with and women that they want to marry.
In fairness, feminism has precluded the need for many men to "grow up." Many women are doing for self and loud and proud about it. Many guys have gotten the message. Good-looking guys who have their shit together and are not gay are the rare jewels, not women who want to get married, which is most. Why settle down in 2017? Notice I say "many" not "all," and just playing Devil's Advocate here
For those that didn't grow up with enough brothers, learn how to actually be a friend. There. Just turned up the difficulty level times 1000.
If I ever do online dating I'm surely asking that question. Its just as important as "how many kids do you have." Lol
