>>281258560 (OP)Denji is a complex character. For him, sex partially represents the achievement of a normal life, but not completely since he was ready to throw away his normal life for a chance to become Chainsaw Man again and hook up with lots of girls. It also partially represents human connection, but not entirely since he was ready to sever his connection to Nayuta when it got in the way of, you guessed it, getting attention as Chainsaw Man. He isn't interested in sex solely for the sake of it since, if he was, he would've done it with Himeno or Power, and he didn't.
