Unconventional AF

The hubby and I always joke about getting a girlfriend (my only serious relationships were always with women before he and I met) but lately it's being talked about much more seriously. I'm really excited about the thought but concerned at the same time because it's so untraditional. Plus like how do you even go about getting a girlfriend together as a married couple or explaining it to family or our son when he's old enough to understand. It sounds so great but the logistics of it all is kind of stressing me out.
