I mean, I'd be flattered if I were dating someone and his mother and grandmother liked me enough to let me in their kitchen, but I come from a tradition where a kitchen is someone's personal space and letting someone else into it, much less letting them cook, is a huge sign of trust and acceptance. I would probably not let someone who'd only been around for three years into my kitchen unless I thought they were really great. So...even if you come from a tradition like mine, expecting someone you aren't already close with to come in the kitchen and help is weird. Never mind the gross gendered stuff.
