Try this; use some clippers & trim them back. Go for a day or two & see what she thinks. If she still wants to see what you'd be like shaved, then shave. What's the worst that could happen? She doesn't like it? You don't like it? Guess what...they'll grow back! Either way, it's fun to try new things & experiment. Personally; I keep 'em trimmed. Funny thing though - the hair on my head is shorter than my pubes.
