What would happen if you just said, "I'm horny" and walked away or dropped the subject. You tell her and leave it at that. She'll know you are, she'll realize you don't expect her to do something about it immediately, and she'll realize how often you think of her in a sexual way. Safe and effective. Maybe change, "I'm horny" to "I want you" or "I want to be with you"....Like HP said, try it for a week. She may find some humor in it anyway....
Each experience in life has formed me, become part of me, made me stronger.
