It all depends to the attitude to the sock buying IMO.
Yes I buy socks for DH. DH also buys socks for himself, and sometimes socks for me. If he viewed sock buying as a piece of domestic trivia which was far too important for the owner of the almighty penis to engage in,he would have very cold feet. And a very cold bed.
There's also an element of infantilisation to some of the posts on here, as if the ownership of the almighty penis means subnormal intelligence when it comes to the purchase of basic items.
If thoses attitudes are avoided on both sides, then sock purchasing shouldn't be a feminist issue.
