We do like to see Don’s sex life in season openers. In fact, Don has had explicit sex in every season opener (except in Season 2, where he tried, and failed, to have explicit sex).
- Smoke Gets in Your Eyes had Don in bed with Midge, and the “I love you Grandma” striptease.
- Season 2, For Those Who Think Young, has Don and Betty at the hotel for Valentine’s Day, and an unprecedented bout of impotence.
- Season 3’s opener, Out of Town, gives us Shelly the stewardess in Baltimore (although the really hot sex in that episode is between Sal and the bellhop).
- Season 4, Public Relations, is Don having a prostitute slap him.
- Season 5, A Little Kiss Part 2, had the kinky, sexy, “you don’t get to have this” scene with Megan.
- Season 6, The Doorway, has Don and Megan in Hawaii in Part 1, and the reveal of Don and Sylvia in bed in Part 2.
- Season 7 opens with Don and Megan first failing to have sex and finally succeeding in their L.A. weekend in Time Zones.
- Finally, Season 7.2, Severance, has Don having sex with pretty much everyone, but the two explicit scenes are with Di the waitress, and Trish the stewardess.
In Season 5’s Mystery Date, hallucination-Andrea said that sex was meaningless, something that Don himself echoes the next season, to Betty, in The Better Half.
In Mystery Date, Andrea’s last words before being strangled were to tell Don he was “sick, sick”. From the playful version of “sick,” we can see Don likes to explore the darker side of things; dominating Sylvia, being dominated by the prostitute, and playing some complex sex games with Megan. But his hallucination was surely about the less erotic side of “sick.” At some level, Don still believes in the religion of his childhood (as has come up several times over the years), and he has a lot of self-hatred.
All this, of course, makes me wonder how many episodes there were in which Don didn’t have sex, but that’s a complex accounting for another day.
