I don't really want either removed but the appeal is the power the fantasy women has. Your balls or dick don't belong to you, there hers. She can band the balls and decide how long to leave them banded, long or to long. Same with penectomy. She's got your goods in the garden shears and does she pinch it just till it hurts or will you see a sparkle in her eye as she as she flicks the wrist just a little more.
