Movies like Eight Days a Week

Peter loves his next door neighbour Erica and, on the advice of his grandfather, decides to camp out on her front lawn for the entire summer, or until she agrees to go out with him. His father is none too happy about the idea and refuses to let his son back in the house, even to get a change of clothes. Peter's friend, Matt, thinks Peter should give up on women (like he has) and just have sex with fruit, and have a total devotion to masterbation.
