HELP Valentine's Day

Me and my boyfriend are living together. We don't plan on doing anything too crazy on Valentine's Day. Maybe make dinner together. I was going to wear a sexy dress but can't imagine him having sex with me right then and there. (He usually likes to have sex in bed and we'll start dinner around 5) I really wanted to wear lingerie underneath but now I'm thinking that I should wear this and cook in it instead with him because then I don't have to wear a fancy dress and can just be comfy but still sexy. What do y'all think?! Or what could I wear over it?
