BUT ... traditional westerns were also romances - low key, guy gets girl after the bad guys are done in, and certainly no more than a gentle peck on the cheek. That was one of the basic premises.
So, my opinion, if a current writer avoids all the modern passionate kisses and roving hands, the story could probably still fit the classic western scheme. Think John Wayne movies - if your story could have become one of his movies, you're probably still okay as a western; if your male MC is more like whoever the "hunk" was who starred in 300, then you're probably more over to the romance side.
