Since Steve's testicular amputation, balls are a sensitive subject; he even wants a prosthesis, however supportive Miranda insists they don't matter to women. Now his movie star- girlfriend has dumped him, Carrie must receive heart-broken Mr. Big at pissed-off Aidan's cabin. Trey is offended when Charlotte insists to have his sperm quality tested and needs personal encouragement once he's in the boot. Samantha wants a job from hotel tycoon Richard Wright, but fears that he refuses to hire a woman.

When Carrie's apartment is going co-op, Aidan proposes they buy it together. She finds a ring in his things, and accidentally insults Miranda who helped pick it out. Trey's MD tries to control Charlotte's reproductive zeal in light of the tough statistics of in vitro fertilization, and Charlotte looks into adopting a girl from China. At the annual Highland Fling, Bunny's objection to a 'Mandarin granddaughter' causes a marital row. Samantha finds out Richard Wright is a tough boss but into quick sexy without commitment, such as on a flight to Rio. Miranda tells Steve he's becoming a father but that she doesn't expect his help.

Carrie finds living together with Aidan cramps their space, literally as well as figuratively in secret singular behavior. Samantha is hot enough on Richard to give him a blow job, even in his glass wall-office, but resists any romance. Trey is ready to get on with life without a baby, but Charlotte is offended by any alternative and throws a ladies night which ends quickly as they witness a livid marital row. Miranda has a last hot sex partner, Walker Lewis, before her pregnancy is too far advanced.

The girls spend a hot night at the gay club Trade, dancing in a sea of bare-chest good-looking men. Carrie meets sexy, Australian shoe importer -wow!- Oliver Spencer, to Stanford's envy. Samantha gets so high on beefcake, XTC and naked dicks in the gents (no girls there) that she tells Richard during hot sex she loves him, but gets no response. Charlotte is presented in the club to Anthony's boyfriend Gordon, who works for 'House and Garden' magazine, and arranges for it to take pictures at her place, the house of a 'perfect couple' - but Trey's lack of interest for yet another thing that excites her pushes their relationship to effective separation. Miranda's pregnancy becomes known at her law firm when a young colleague Max means to defend so her dozing off, but they're overheard when she says to what it no more out then his being gay (as she saw him in Trade)- the next day they both come clean.

In order to get over her divorce, Charlotte takes up tap-dancing, but it doesn't solve her emotional state. Richard has enough confidence to admit doing it with Bebe and invite Samantha to join him in the luxury shower in one breath; she obliges, but still is vexed enough to have a quickie just to spite Richard, who doesn't bother. Aidan joins his fiancée Carrie in their smaller shower. Miranda learns from her gynecologist the baby is a boy, and is terrified not to be flooded by maternal feelings. The two brides go wedding shopping together, but Carrie chokes in a dress, an extreme symptom of wedding gibbers, or is it more serious?

Carrie has an opportunity to buy her apartment since it's going coop, but without her ex-fiancé Aidan can't get enough capital together, so she must consider a cheaper lifestyle; Miranda calculates she wasted some $40,000 on her shoe obsession. Samantha takes a Chanel bag and other luxury gifts from Richard as a declaration of love, till she realizes how impersonal the cards are. Charlotte wanted to get her wedding ring converted to a necklace, but the words 'melt it down' make her realize she's not that ready yet. Realizing her financial misery after seeing unaffordable apartments she wouldn't even want, Carrie considers accepting a loan from Big, but after Sam and Miranda say they would rather spring her themselves tears up his check. Charlotte takes a volunteer job in the museum, and Carrie, who can only get freelance work with Vogue, works her frustrations out on the rich girl, who tells her off to manage her own finances like an adult. Taking a bath in Richards apartment, Sam bumps on his gay personal shopper Roger, and makes him put in a card mentioning love for a change. Pregnancy-horny Miranda talks Steve into giving her multiple orgasms, but 'no strings'. Charlotte gives her ring to Carrie for a down-payment, so the contract is signed.

Carrie presents her first free-lance article to the Vogue editors, who react completely differently: Enid barks it's simply 'her column', so 'not Vogue', but Julian takes to her - perhaps even too much. Richard says he doesn't want to celebrate his birthday but Samantha insists he picks a gift, and he chooses a threesome with a young waitress. When Miranda complains about getting things for her future baby, Charlotte - who is mourning her own motherhood ambition - offers to throw her a baby-shower but is instructed to keep it low-key, almost businesslike, without the usual baby theme.

Big tells Carrie he's moving to Napa Valley, but their last night together is interrupted when Miranda goes into labor; Samantha suspects Richard of cheating.

Miranda is determined not to become a mental full-time-mother, but the reality of breastfeeding is inescapable. Charlotte blurts out to believe the theory everyone only gets two great loves. Carrie is alone but determined to enjoy the countless forms of entertainment in New York, even claiming she's in love with the unpredictable city. After three weeks of calls from Richard, Samantha is out for revenge, and in public. Fortunately it's fleet week, when the city swarms with USNavy boys, who invite the non-moms to a hot party.

Samantha's announcement she's giving Richard another chance after his unfaithfulness, as nobody's perfect and it was 'only sex', is such a bomb-shell that even Charlotte makes an obscene gesture. Although Miranda is atheist, she can't deny Steve's entire Catholic family having the baby baptized. Just when Carrie felt down having to write about relationships without having one herself, she gets invited by a publisher to select some of her columns as a book. Eternally positive Charlotte drags Carrie along to the Fountain of Faith, but stands up to say faith didn't suffice for her.

Carrie is bored as if there was no entertainment anywhere in New York, so she insists on celebrating Charlotte's 36th birthday together; Samantha had promised Richard to join him to Atlantic City, but when she tells him he invites the whole quartet to the Taj Mahal casino. Miranda and Carrie, who came to get her, miss his private jet because Steve is really afraid to take care of Brady for more then two hours, till Magda offers to help. Once there, Charlotte lives it up and Miranda switches between gambling and getting ready for bed, but Samantha can't handle the fact Richard seems to know all female staff intimately.

After three weeks, Carrie gets a written invitation from Aleksandr; they start flirting and end up in bed. Charlotte looks for a new perfume and a volunteer career while waiting for another pregnancy. Miranda would be happy back with Steve, but keeps bumping into unforgiving yesterday's perfect man Robert. Samantha didn't feel like accompanying Smith to a Teen Girl party- till she reads it's hosted by her ex Richard Wright; she tells Smith they should each play with their own friends, but is greatly relieved to find him waiting for her anyway.
