I wouldn't mind an attractive cleaner. I'd never need a full housekeeper so a cleaner would only be in a few times a week to do that specific task. that's like 4-5 hrs a week at most. If he can't control himself around someone he's only gonna see for 2 hours a couple times a week, probably with me there with him? Nah.
An attractive nanny, again I would never need someone full-time. At most, she'd be picking up the kids from school and getting them settled so that we aint gotta leave work early. therefore we'd only see her for an hour at most, she'd be there when we aint. Hiring beautiful women aint an issue.
I think this poses more of an issue for people who would be spending significant time alone with this staff. If I needed a live-in nanny or wanted a full or part time housekeeper, my answer would probably be different. They could start bonding while I'm on a business trip or something.
