Well, if we consider that Pulp Fiction is known for its unique and often unexpected dialogue and scenes. In some cultures, pork has different connotations. It could be that the 'pork discussion' might be related to a hidden or symbolic meaning within the movie. For example, if there were characters discussing food and pork came up, it could be used to show their cultural background or personal preferences. However, I don't recall any very prominent pork - related discussions in the movie off - hand.
In the mainstream comics, Venom's sexuality is not defined as gay. His character development is centered around battles and conflicts rather than his sexual orientation.
It depends on the specific comic and its storyline. Sometimes it might be explicitly shown or hinted at, while in others there might be no clear indication.
