Is it weird to go lingerie shopping with your auntie?

My auntie knows that I’ve been wearing lingerie since I was 15.
she’s know since I was 17, and she’s totally cool with it and supports me with it and been so helpful.
after she found out that I didn’t have my own and I was wearing both my stepsisters thongs and my mums she took me to shop and bought some underwear for me so I had my own, she let me pick which ones I liked them bought me them.
since then we’ve always gone lingerie shopping together for us both and even picked stuff out for each other.
Told my close friend about it and he thinks it’s weird that I go lingerie shopping with my auntie
