challenge, contend for, make love to
挑 centers on confronting something head-on: challenging, contending for a goal, or making a bold advance. The 'make love to' sense is a specific, intimate application of that forward, provocative energy.
挑 combines 扌 (hand) with 兆, which likely contributes the sound and the idea of a sign or omen, suggesting a hand raised in challenge or provocation.
A hand 扌 beside 兆, which looks like a sign or omen. Picture a hand raising a challenge flag, provoking a contest or a bold advance.
For チョウ, imagine a challenger named Chou raising his hand to contend: Chou -> チョウ, and his hand 扌 issues the challenge.
