Human males will always attach their penises to food production(or anything else women want or need) so that they can get women to have sex with them. The human male attaches his penis to a cure for a disease and ask women "Do you like that cure for that disease? Well then, go ahead and rub up against it."

He should take her out and do some parkour with her for stimulation(since it is free). He should also stop being proactively "romantic" with her whenever she is not giving positive feedback to him.
