The Big C: "Sexual Healing"

Well it was the sex episode tonight. Was it good for you?
Things have been going so well for Cathy and Paul this season, I was curious to see how her affair with Lenny in Season 1 would factor into this episode (as hinted in the “previously on The Big C” episode teaser.) Never fear: things are by and large still fine between the Jamisons—they’re just trying to figure out how to get their sex on. After Paul gives Cathy her steroid shot, he starts making the moves on her (insert needle-dick joke here. Now insert "insert" joke here.) Cathy’s not feeling up to it, though, and so Paul reassures her, “We have a lot on our plates right now. We’re not teenagers: I don’t miss it!” Which to me doesn’t sound very reassuring: I think you’d want your husband to miss having sex with you, but just be able to deal with it somehow.
Andrea’s parents have very suddenly discovered they’re being sent to Ghana for missionary work, so Cathy invites her to stay with them, despite Paul’s semi-ambivalence about the situation. In a somewhat predictable turn, Andrea runs into Paul masturbating to a Victoria’s Secret catalog. It’s all good between the two of them eventually, but Cathy catches wind of it and confronts Paul about his lie about not missing sex. For some reason he throws her affair with Lenny in her face, and Cathy points out that he had an affair as well. I suppose the old affairs will come back around later in the season: is Tina possibly pregnant? I’m guessing Lenny isn’t.
After Cathy’s pep talk to him last week, Sean’s on antidepressants and so chipper I assumed that he was lying the entire episode about being on them (but I don’t think that’s the case, at least so far.) After nailing love to Rebecca, he waxes on about his favorite parts of her body, which include her nipple hairs and butt dimples. I don’t know how she must feel like since I have a perfect body, but I think she overreacted just the tiniest bit. Obviously Sean was Rebecca her in his weird way, and you’d think she knew by now that Sean has odd tastes (like making their own toilet paper.)
