[any] Small question on corruption

Alright, I have a tiny dilemma: I’m playing a corruption based creature (similar to a succubus, but the act isn’t necessary. Just getting stronger trough corruption of every mean). Now the thing is, a person attracted to younger people has more corruption potential, but at the same time if my character will look like the type those people are attracted to, it’ll basically be "yeah, actually she’s 500 years old (my character is younger, but I hope you get the point)". What other means of quick corruption are there, that don’t involve dipping into "that-guy/creep" territory (or, at least, not as far as using a underage body for those)?

Edit. I know that "Just use a legal-age body" is a solution, but maybe Reddit has a faster and more efficient way.
