I'm not entirely sure what specific 'Sex Pulp Fiction' you are referring to. It could potentially be a sub - genre within pulp fiction that might deal with sexual themes in a more lurid or sensational way, but without more context it's hard to define precisely.
If we think about 'Sex Pulp Fiction', it could be a form of pulp literature that uses sexual elements as a main selling point. Pulp fiction was known for its mass - produced, cheaply made nature, often with lurid covers and exciting, if not always high - quality, stories. 'Sex pulp fiction' might have exploited sexual content to attract readers, perhaps containing stories of seduction, passion, and sexual intrigue. However, this is a very general speculation without more detailed knowledge of the specific work or genre you mean.
