If you set aside the fact that everyone needs to learn basics for supporting themselves. As a relationship skill, it's actually worthless for men. The majority of men either don't know or will not cook anything let alone develop the skills further for home. If they are professionally doing it that's fine.
I have seen most women don't mind cooking for the guys they love and men marry women for their housing and cooking skills. Even, several of my recent friends have done so. But as a man, your cooking skills can do nothing. Women do like the idea of men cooking for them but they will not eventually date them for that.
