I have taken my husband's surname both times I married. It was entirely my choice and I felt it was the right thing to do regardless of whether we had children.
My DH is totally alpha male but offered to take my surname in car on the way to the reception after our marriage service. We hadn't discussed it before. I then pointed out that it was actually, technically, my ex husband's surname but that I'd never got round to reverting back to my maiden name. Didn't bother him though!
We are settled on his surname now (took me years to update my previous married name to my current married name).
Btw, I am an ultra feminist and also the breadwinner, with my husband the SAHD, but see no issue in using his surname.
Just do whatever you want and don't worry about posturing or what anyone else thinks.
