Its impossible for us to know what ANYONE would have thought about unmarried people IN LOVE doing the deed, certainly it would be better for all if they were married (less complications), but the fact that there were prostitutes around means that Lust found a way, lol !
I guess my question was what Paul had in mind when he said "fornication"... Of course, this gives leeway for people to view it anyway they want since Paul wasn't specific and then lord it over people such as the BORG does... According to Strong's dictionary, I would have to believe like you that it was a lot more to then just doing the deed before marriage and such. This is how Strong's defines it:
a (male) prostitute (as venal), i.e. (by analogy) a debauchee (libertine):--fornicator, whoremonger.
debauchee is "a person addicted to excessive indulgence in sensual pleasures; one given to debauchery."
