I'd support an "absolute" age of consent around 25, with consent for lower ages being based on age ranges (say, 1 year for 15-year-olds, 2 years for people aged 16 or 17, 3 years for people aged 18-20, and 5 years for people aged 21-24).
This is an extremely invasive and disturbing pov. Seriously, wtf is wrong with you?
My parents have a seven year age gap. When they met, my mom was 21 and dad 28. They've been together for 45 years and married for 40. Their relationship is incredibly healthy and equitable. But in your world my father would've been taken away by cops and labeled a sex offender. Nice.
