All right, how's this?

My powers are rooted in human romance.

I have the ability to let people see their crushes naked.

Does that really count as romance?

Heheh... But you're a fine, hot-blooded young man, aren't you? I'll bet there's someone you've got your eye on...

*doooooom*

I'm going to cast a curse on you so you'll only see her in her underwear from now on!

*shwooom*

You won't be able to control your furious adolescent erection! Your life will become a living hell of constantly trying to hide the bulge in your pants!
