Advice on Sex

So I’m hoping I can get some help here.

1) I can not talk about sex with my partner, and it bothers both of us. He’ll start asking me questions about what I like/don’t like, and I just clam up and I hate it because I want to tell him but my anxiety just gets the best of me EVERY TIME. I don’t even know why I have anxiety. I love my partner and we have a great emotional and physical relationship

I think it’s also partially that I don’t know how to talk about sex per say? Like I guess I want to sound sexy but when it comes down to it I guess I should just say it and let it sound however it does
