in most us states the age of consent is 16 or 17 i have no idea how the "age gap" thing suddenly became so weird hell even if you follow the stupid "half your age plus seven" rule, a 22 year old is still totally in the clear to date an 18 year old but ultimately if two people above the age of consent want to date it's nobody's fucking business. if a 16 year old and a 66 year old want to date and it's legal then shut the fuck up. with all that said the actual age of consent should simply be "marriage"
