Joan grows impatient with Sean, who refuses to kiss or touch her. After discussing a number of possible explanations with her friends, she finally pushes Sean for the reason behind his cold behavior. Joan is taken aback when he confesses to being a sex addict. Meanwhile, Toni annoys Greg with her refusal to make a commitment to him; and Yvonne angers William by sharing a few too many intimate details about their love life with Maya.

Yvonne panics when William seems hesitant to set a wedding date, as she fears that he is getting cold feet. A very reluctant Joan finds herself caught in the middle of the couple's relationship problems. After a chance meeting at a restaurant, Toni declares her love for Greg and manages to win him back. Lynn and Maya try to arrange a friendship between Darnell and Vosco in the hopes that their good qualities will rub off on each other.

On her 30th birthday, Joan grows depressed at the realization that she hasn't had a lot of excitement in her life. She determines that she will live life to its fullest in her thirties, and demonstrates her new philosophy by taking her friends to a nude beach--where they run into her father. Meanwhile, William suggests a pre-nuptial agreement to Yvonne, and is surprised by her response.
