One of my high-school classmates married one of our former teachers. She had just turned 18. He was 39. Three decades and three kids later they’re still together.
If her parents approve and she is willing, there is nothing sinister about it at all. Funny how liberals don’t mind introducing grade school and middle school children to sex education (which goes way beyond basic biology) but now we are supposed to clutch our pearls because a 30-something man is interested in a woman who is still a teen, that is disingenuous at best. These men were interested in marriage which is an honorable intention.
