Now that you mention it...

I don't think a man hurt Gothel. I think it was just another tool in her arsenal to keep Rapunzel in the tower. I mean Rapunzel was 18 at that point, she had to have been having womanly urges. But if Gothel could shame those urges, and make Rapunzel fear them, it served as just another way to keep her under control.

I think ignoring all that, and saying Gothel had issues with men sorta devalues her character. I mean she might have had trouble with them, but I think the main problem might have been herself, given how narcissistic she is.

I always assumed she worked in the sexual business, tbh. she doesn't seem too much of a witch to me (no magical powers, potions, etc).

Then again she could also be like a sort of mother like Carrie's mom.

I've always thought so. But Aang_Lite makes a good point against it.
