Does anyone have a recommendation for an electric personal groomer/trimmer for their pubic area? I used to have a great Panasonic one, but it broke. Now I've bought two others, but they tend to nick me on the softer parts like testicles... I was shaving, but the wife didn't like the stubble after a day and I just can't keep up with it reliably for our frequency of being together. So she likes it really short, but not stubble short. Trimmed nice and neat. Any suggestions?
