Yes, there is a kissing scene in Venom.
Near the end of the film, during a crucial moment, Venom temporarily transfers from Eddie Brock to Anne Weying (Eddie's ex-fiancee) to help them escape. This transfer is depicted through a kissing scene between Anne and Eddie. The kiss is the mechanism through which Venom moves between hosts. While not a romantic kiss in the traditional sense, it is a necessary kiss for the plot and action.
