Denji wants to have sex, that is true, but it's never ever been established that he wants to have sex without Asa's consent.
You're just confusing the order of panels in ch 193 or something. He nodded his head when asked about whether he wants to have sex, but his reaction to Yoru's sex deal is left ambiguous.
He already had a free pass from Asa previously and he preferred to go on a date instead. That's partly why she fell for him.
