I have a worryingly large amount of experience on this topic because I was the younger partner multiple times. It, uh, kind of worked sometimes? Like it wasn't great. I was super young. I was really dumb and did a lot of stupid things because I was horny. It was all legal! So I dated, more or less consecutively (month or so gap in between):
- a 35-year-old when I was 16-17, long-distance, for 1 year (least okay, this was really fucked up)
- a 21-year-old when I was 17, medium-distance, for like 2 months (not super okay. ended in a meltdown, not good because he was in college and I was not)
- a 27-year-old when I was 18, close-distance then long-distance, for 1 year (actually was the most okay by far, turned not okay when I--surprise--went to college)
