Mild implied sex with male topless nudity

In Season 4, the f-word was uttered a couple of times. However, Season 5 and 6 have the f-word in every episode, as well as other curse words and blasphemies such as "Christ" and "Jesus". The language seems to have gotten progressively cruder and vulgar over the years. Now, we have even the main character uttering the f-word, and words such as "shit", "bastard" etc.

Season 1 has blasphemies such as "Christ"

Season 6 has constant TV-MA level profanity not experienced in previous seasons. Frequent F-bombs throughout every episode. (Way past Prime's rating of TV-14.)

The language gradually increases with each season, and becomes especially frequent and vulgar in Season 6.
