A poll of 1,400 self-confessed love cheats found that 72% said their relationship with their husband or wife had “improved dramatically” since they started an affair.
A total of 52% even said their sex lives with their spouse had seen an uptick since they started cheating on them.
Some said that rather than having intercourse just once or twice-a-month with their partner, they did so up to six times a month, three times more than usual.
At the same time they were romping with their secret lover at least six times a month.
The study by extramarital dating site illicitencounters.com found that nine-in-ten of those polled who were having a fling admitted still having sex with their partner.
Asked if their relationship had been “better” since they started an affair, 72% said it had “improved dramatically”, 2% said it had become worse and 26% said there was no noticeable change.
Asked if they had more or less sex with their partner since starting an affair, 52% said they did, with just 23% saying they had less sex, and 25% saying it stayed around the same.
A spokeswoman for Illicit Encounters said: “We polled 1,400 married members to see what effect having an affair has had on their relationship at home. We found that 72% of married people say they’re happier in their marriage since starting an affair, and of those, 52% said they’re actually having more sex than ever with their spouses.”
