Sirius arched an eyebrow in Lily's direction when she drank down a glass of some very old and likely expensive wine like it had come from the market round the corner and then poured herself a second glass, he had an amused grin on his face though despite that fact.
"As far as I know two men still cannot have children together, Lils, so don't go getting yourself all worked up over that." He smirked at her and shrugged. "It is still impossible in the traditional sense." And Sirius really wasn't sure he wanted to think about a future possibility where men were the ones being pregnant.
"I'm not sure yet." He told her. "I think if we do decide to have children we'll want them to be ours, related to us. James has looked into some muggle methods they have right now, it's kind of amazing really what they do, but they can make a baby without there being any sex involved." He held up his hands like it was some sort of crazy miracle or something.
