62% of men and 37% of women over the age of 65 are sexually active, according to a Spanish study published in Sexual Medicine. Nearly 2,000 people took part in the study, who described the frequency of their sexual contacts and their daily habits. The researchers analyzed the factors that influence the sexual activity of the volunteers and found that the lack of intercourse was mainly due to physical illness and not to age criteria. The most common love caresses among people of this age are kissing and sexual intercourse, the least practiced is masturbation and oral sex. Other similar studies show that 60% of people over 65 have sex an average of four times a month. There are various factors that can reduce sexual desire and activity, such as maintaining poor personal hygiene, taking medications, typical of people over the age of 70, etc. Some people worry that sex can also increase the risk of heart problems. . But in a recent study, scientists found that sex slightly increases the risk of heart attack, as does climbing stairs. The risk of a heart attack during intercourse is only 1% of all possible causes of heart attack, the researchers explain.
