I believe a girl can have many types of underwear for different occasions. My girlfriend wears only a sports bra during sports training, which fixes her large breasts well. But during romantic evenings, she wears erotic underwear sets that I gave her. I found it all on https://www.blackalice.co.uk/ when I gave her gifts of this kind. Of course, I can show her photos of what I like before buying. We openly discuss this in a chat or in a conversation. What do you think about a couple discussing each other's underwear? I think it's important in a relationship to say what attracts you and what doesn't.
