Do you all share underwear with your gf?

I’m genuinely curious if this is only me and my gf. We’ve been together for almost 6 years. Slowly she started just wearing all of my underwear and it’s to the point that she doesn’t even buy underwear for herself anymore. We only have one underwear drawer. It lowkey kinda makes me feel weird sometimes, like once in a while okay cute but we literally share all of our daily underwear at this point. Like I bought period underwear for myself when I’m on my period and she wears them when she’s on hers and I’m just like 🥴 So does anyone else completely share undies with their gf?
