I think the assumption that a huge football player has more power in the relationship than his tiny cheerleader girlfriend is equally justified. Certainly it isn’t true in all cases, of course, but neither is it true that a child would be intimidated in a relationship.
And this depends on how you define ‘child’. I don’t advocate legalizing a sexual relationship between a 10-year-old and a 50-year-old, but I see no problem with changing the age of consent to 13, adding maybe a 1-year swing factor, and looking at the circumstances in each case.
