I have more than once gotten dressed up and done housework around our house. Not for more than a day at a time and I'm married so I'm not going to go over and stay with someone and do that sort of thing I don't think my wife would appreciate me doing that for someone else. I feel like if this is your fantasy and it's something you want to try and you can be sure you are safe and the guy is sane then go do it. Don't worry about how sexist or anything it may be to others after all it's just something for you, your fantasy not like you are saying to world it should be this way.
