user: Article: Barry McCarthy, 50, denies murdering Lorna McCarthy, also 50, who was found dead at their marital home in Gorleston, Norfolk, in September.
Norwich Crown Court was told Mrs McCarthy and the man had agreed to have sex a week before she died.
They had exchanged text messages and calls and planned to meet in October.
The court heard statements, read by the prosecution, from men who Mrs McCarthy contacted on websites.
The jury was told of another man who said Mrs McCarthy had called him as she walked home in the hours leading up to her death.
She told him she was not looking forward to what was waiting for her, but she did not say she felt unsafe or in danger.
The court also heard a statement from forensic medical examiner Dr Franciscus Bohncke who saw Mr McCarthy in the hours after his wife's death.
He said Mr McCarthy was emotionally upset by his actions but fit for interview that day.
Previously, the court heard Mrs McCarthy was found with several stab wounds including one through the heart.
The jury listened to a police recording where Mr McCarthy admitted to killing his wife.
The couple had split up a few months earlier but were still living together in Sussex Road in the town.
Mrs McCarthy worked for a charity and was well known in the Great Yarmouth area.
The case continues.

Problem: The Houthis ousted President Abdrabbuh Mansour Hadi last month, who fled to the southern port city of Aden where he established a rival power base.
At the weekend, the Houthis seized Taiz, Yemen's third largest city, bringing them closer to Aden.
The UN has warned that Yemen is on the edge of civil war.
Mr Hadi's Foreign Minister Riad Yassin told the Saudi-owned Asharq al-Awsat newspaper he asked the six-nation Gulf Cooperation Council (GCC) to intervene, without elaborating what that would mean.
He also said he had asked the UN and GCC to impose a no-fly zone, after warplanes hit the presidential palace in Aden over the weekend.
The Houthis' rise has alarmed the GCC, and in particular Sunni-controlled Saudi Arabia, which accuses the Houthis of being a proxy for their key regional rival, Shia-majority Iran. Both of them have denied the Saudi claims.
Yemen - who is fighting whom?
The Houthis: A minority Shia from the north, the group seized control of Sanaa last year and have since been expanding their control.
President Hadi: Backed by military and police loyalists, and by militia known as Popular Resistance Committees, he is trying to fight back against the rebels from his stronghold in the south.
Al-Qaeda in the Arabian Peninsula: Seen by the US as the most dangerous branch of Al-Qaeda, AQAP opposes both the Houthis and forces loyal to President Hadi.
Islamic State: A Yemeni affiliate of IS has recently emerged, which seeks to eclipse AQAP.
Also on Monday, the Saudi foreign minister warned the Gulf states could take action to shore-up Mr Hadi.
"If this issue is not solved peacefully, we will take the necessary measures to protect the region from their aggression," said Saud al-Faisal.
The UN envoy to Yemen, Jamal Benomar told the BBC the Saudis had "good reasons" to be concerned about the situation.
But he added: "I don't think any side could win a civil war. No side can win a civil war - the only way forward is negotiation, which implies concession from all sides, which implies also, a compromise."
Britain has meanwhile joined the US in withdrawing special military forces from Yemen because of the deteriorating situation there.
Further deepening the crisis, Islamic State (IS) militants appear to have emerged as a presence in Yemen.
A purported local IS affiliate says it was behind an attack that left 29 dead in Lahj, north of Aden, after another branch claimed the suicide attacks last week in Sanaa that left more than 100 people dead.

The boy has not been seen for two days, after his parents left him alone because he misbehaved.
The couple initially told police he got lost as they foraged for vegetables.
But on Sunday, they admitted they left him alone for a few minutes to discipline him, and when they returned he had gone.
The boy's father told the Sankei newspaper on Saturday: "I wanted to discipline him, so made him get out of the car to scare him a bit. He's an active, lively boy, but I'm worried how he's doing."
He told reporters the boy had thrown stones at cars and people during a visit to a nearby park, so he felt he needed to be a strong father.
He also told a TV Asahi reporter he did not dare admit the truth when he first requested the search.
Monday's search began at 06:00 local time (21:00 GMT Sunday), involving 130 people, including police and school officials, local media reported.
The area, in the far north of Japan, is home to wild bears.

Sum: The search has resumed for a Japanese seven-year-old boy who was left by his parents in woods in a remote area of Hokkaido as a punishment.

Problem: The Bureau of Labor Statistics reported that US firms created 223,000 new jobs in April, while the unemployment rate dropped to a seven-year low of 5.4%.
The Dow Jones jumped 267.05 points, or 1.49%, to 18,191.11.
The S&P 500 index rose 28.10 points to 2,116.10, while the Nasdaq added 58.00 points to finish at 5,003.55.
April's strong jobs increase followed a rise of just 85,000 jobs in March, when cold weather was blamed for hurting the US economy.
"This is one of the most encouraging jobs reports that we have seen in years, because it shows that the recovery in the US labour market is no flash in the pan," said Ranko Berich, head of market analysis at Monex Europe.
"Last month's figures were well below expectations, leading many to worry whether the cold winter would lead to a permanent slowdown in jobs growth. April's report puts these worries to rest," he added.
However, some analysts said the US Federal Reserve would want to see more signs that the recovery was being maintained before raising interest rates.
US benchmark interest rates have been near zero since late 2008 when the central bank slashed rates during the financial crisis.
US fast food firm Bojangles made a strong start when it debuted on US markets on Friday. Shares in the firm rose over 40% after initially pricing at $19 per share, which valued the restaurant firm at $680m.
Shares in credit card firm Visa were the day's biggest winner on the Dow Jones, rising over 4% after Bloomberg reported that it was in talks to buy its former subsidiary, Visa Europe.
But online staffing firm Salesforce.com suffered the opposite fate.
Shares in the company rose sharply earlier in the week amid rumours that the firm was going to be acquired by Microsoft.
But they declined by nearly 3% on Friday after online publication Recode said that Microsoft denied the reports, citing unnamed sources.
