Girls, how would you feel if your boyfriend likes wearing womens underwear?

Im a 19 year old guy. Im not gay or bi, I just like wearing women's underwear. Its more comfortable, and I like how they look so why not? My girlfriend sort of understands this, and was ok with letting me buy a few pairs. But now she feels like im taking something away from her. She feels like theres no point in her wearing sexy undies because I do too, and its something that was previously just hers. I love seeing her in lingerie just as much as I did before I wore girls underwear. Anyway, how would you girls feel if your boyfriend wore these?
