Don't know who got it wrong - the people translating or the people writing it.
This (above) is not a water nymph. This is someone(s) who is trying to impress/satisfy a man through sex. Or get paid. This should just be a picture of her sexually worshiping and lapping through the waves of money, cause that's what she wants.
Obviously drawn by a man.

That's porn.
Porn. Porn. (use your imagination or google image)
Someone who's a water nymph, not a porn star, not a sex addict, loves sex but is just a little bit more in love with the water than she is with sex. It's a close call, but she loves water a little bit more. She wants them both, but she would choose the water over the sex. Sex - water = nothing. Water - sex = sexy. She's a water nymph. She's not a sex slave.
