Love is in the air, with Ben plagued with unexpected doubts about his ability in the sack, while a miscommunication between Dave and Julie in the bedroom department sends her into a frenzy of frustration. Ben's basking in the joys of married life when he hears those words every husband dreads - 'not tonight dear, I've got a headache'. Terrified the honeymoon is over, he embarks on a mission to sweep Melissa off her feet. But all of his attempts at rekindling romance are thwarted by Melissa's concern for Sammy, who seems to be spiralling deeper into depression. When Ben shelves his plans to come to Sammy's rescue, Melissa's reminded how amazing her husband is, and his compassion acts as the aphrodisiac he's been searching for. They hurry for the bedroom, only to find Carbo has organised a retro romantic surprise of his own - with unexpected results! Meanwhile Dave struggles with a sexual issue of a different kind - an embarrassing 'stirring' downstairs while on a job at the boat club. It's the result of months of enforced celibacy due to the new baby, coupled with a photo shoot of swimwear models. Julie's more than keen to resume intimacy but Dave seems strangely reticent. To Dave's embarrassment, Julie shares her frustration during a public outburst at a family luncheon, fuelled by a half- glass of wine. After a series of misunderstandings, Dave finally throws Julie on the bed in a rush of red-blooded abandon - the rest of the house can buy earplugs! While Ben and Dave grapple with the concept of being a good husband, Jake's wrestling with the idea of being a good son. He finally meets Grace's new boyfriend, Doug, and is determined to dislike him from the outset. Needing to escape the situation, Jake comes up with a surprising solution - one that delights Rachel!
