If anything, in practice men are than the rule would designate appropriate.
Now we can see how well the rule corresponds with people’s reported acceptable ages.
Graph of the Half-age-plus-seven rule ("never date anyone under half your age plus 7"), which claims to dictate what age disparity between two people is acceptable in dating/romantic/intimate relationships during the late 20th century / early 21st century (called the "Standard creepiness rule" in the xkcd webcomic).
According to this rule, the age of the younger person should not be less than half the age of the older person plus seven years, so that (for example) no one older than 65 should be in a relationship with anyone younger than 39 and a half, no one older than 22 should be in a relationship with anyone younger than 18, and no one under 14 years of age should be in a relationship at all...
Around their mid-30s, their search preferences include women in their 20s below the age minimum, but by the time they hit 40, these men are back to staying firmly within the acceptable range.
Obviously, the so-called "zone of non-creepiness" is not a hard-and-fast rule; when you are adults of consenting age, no one's going to punish you for violating this arbitrary guideline.
