Peep Show

While Mark tries to glean life skills from a best-selling account of Stalingrad, Jez is firmly fixated on hot action. His life is like a copy of Zoo magazine, and here's a definitive list of the ladies who have succumbed to his louche charm. Warning, there are many!

Toni
Toni finds herself the object of both Jez and Mark's affections, as much by default as for any other reason - she's female, single and lives next door.
Jez is able to use his uncle's death as an emotional crowbar to leverage Toni's sympathy into physical gratification. Fast forward a bit, and a dangerously erotic discussion  with his wife (Nancy - see below) about Robin Williams pushes him and Toni back to the horizontal and into a full-blown affair.

Nancy
Always a fast-mover, it's barely the second series before Jez has found himself a wife.
He first meets Nancy at the Rainbow Rhythms dance group and is immediately taken with the free-spirited beauty.
Her willingness to experiment with new experience is such that she's even prepared to go to bed with Jeremy and then marry him. However, Nancy's view of marriage is not hindered by monogamy, and, to be fair, Jez doesn't do a great job of keeping it in his trousers either. They're meant for each other.

Michelle
Threesome. Wants Jez to be the sex wizard. Supplies her own female assistant. That's all you need to know about Michelle. Every boy's dream (without Jez preferably).

Big Suze
Jez's always significant ex - Big Suze has put him through the wringer a few times by inconsiderately getting into relationships with other men. She took up with the hunk of monk whilst travelling, and also gets together with Johnson, but none of these trivial details is enough to deter Jez from hitting on the poor girl.
A dinner date goes so well that Jez forgets to mention the sexual disease he is currently harbouring, and its business as usual for the troubled couple.

Sarah
Mark's sister Sarah turns up at Apollo House after splitting up with her husband and Jez proclaims himself to be in love. However Sarah's incessant chatter and alarming similarities to her brother soon lead Jez to conclude she's not 'the one.' There's a big surprise.

Carla
Jez puts his libido before the law when he finds himself on the jury for Carla's trial. Ends up banging the defendant before banging her up.

Sophie's Mum
Jez puts his sexual desires before his best friend's marriage when he gets it on with Penny (aka Mrs Chapman, aka Sophie's mum).

Sophie
Jez completes the Chapman double when he follows Big Suze to Kettering to win her back. Complications occur and he accidentally manages to sleep with the one person he's really, really not allowed to – Sophie.

Aurora
During Mark's stag do aboard the Stag Aquatic canal boat, Mark gets pre-occupied with promises of management jobs in India while Jeremy's getting on splendidly with Aurora. Well, he is until he kills her dog and eats it. Hmm, very romantic.

Paula
As demonstrated in past events, Jez enjoys a family affair, so it's no surprise when, in Series Five, he starts dating Paula, the sister of his old flame Toni. Sadly, joyful and infectious love makes way for the realisation that Paula has Chlamydia.

Cally
Not only does Jeremy's band (the legendary - Curse These Metal Hands) get a manager - he manages to sleep with her as well. Sadly, a nagging concern about a new SCART lead impairs his usually exemplary sexual performance, and Cally soon moves on. Can you blame her?
However, it's Mark she moves on to! The couple were moved by their 'shared' love of business (really – business as in suits, stationery, the full works)
You might have thought that such a love rivalry would really irk Jez, but he responds with level-headed maturity - trashing Cally's trailer at a Christian rock festival and blaming it on Mark.
