Is it bad to be seductive to your S/O for women?

I’ve a boyfriend and I’m not sure if being seductive only to him and no other men meant I’m a slut. I know how to be seductive but I might lose my boyfriend if I do. Should I not be seductive and instead be a girlfriend doing girly things. Should I hide this part of me from him forever?

He’s my first boyfriend so I’ve no experience in dating.
