It is the governments role to keep teachers from having sex with their students, not matter their age. The man is a dirty old man. Any 41 year old male that thinks it’s okay to have sex with an 18 year is disgusting.
Why? Both are adults and able to make their own decisions. There is more to love than age or how someone looks.
At 18 I was self sufficient, running my own business and paying for engineering school. I bought my first property and was almost married before the age of 20. Sadly it didn't work out for tragic reasons.
Or is it because you think women should be held to a different standard?
