This comment is childish and immature.
I mean... Go off I guess?
But seriously, check your language whenever you're talking to anyone.
Obviously, the Emperor didn't mean anything dirty. Hell, he even prepared a romantic session for them to enjoy themselves all night. That's cute and all.
However, not only his sentences could be interpreted in a not so subtle "We're f*cking after dinner and for all night", Paul herself is clearly frustrated making her interpret it in the way I cited above.
Knowing that they had a sexual history before a romantic one, the emperor didn't really make it better. Check whether your language can be misinterpreted, even when you think it's unnecessary.
Also, fuck you.
