I’ve just been reading through some reports about sex and older couples. According to one study in America, more than half of those aged 75 to 85 have sex at least twice a month, while nearly a quarter have sex at least once a week. But what’s really interesting is the link with happiness. Only 40 per cent of those who had not had sex in the previous year claimed to be very happy with life, compared with 60 per cent of those who had sex at least once a month. Similarly, while 59 per cent of over 65s said they were happy in what had become sexless marriages, the figure for those who had regular sex was 80 per cent. What the reports don’t tell us is whether it’s the sex that causes the happiness, or the happiness that causes the sex. My guess is that it’s a bit of both.That’s pretty encouraging for those boomers who fear old age as sexless.
