Sex

Sex - Also referred to as humping, FILMS: [Spider-Man: Lost Cause, Spider-Man 2: Another World]

Sex is an activity shared by 2 or more participants in the Lost Cause Universe. It is implied that Richard and Mary Parker had sex to produce Peter Parker, as well as Norman Osborn who had sex in order for Harry Osborn to exist.

It is explicitly stated in Spider-Man 2: Another World that Peter Parker had not yet had sex with anybody in spite of an implied attraction between him and Felicia Hardy (Black Cat) as well as Gwen Stacy.

It was implied when Peter Parker was sent to his future after his death, that Peter Parker would have sex with Mary Jane Watson whom he married prior to his death, as sex is an activity done to consummate a marriage, and the two are married.

It is implied that years after the events of Spider-Man 2: Another World, Peter Parker had unprotected sex with Mary Jane Watson who he will presumably have a child with in Spider-Man 3: Kingdom Come, with this possibly factoring into the title.
