As said by other posters....it depends on the the guy. IMO I don't think its appropriate. I'll be honest - the real problem is, its very difficult living in a house where rooms are rented. Its also hard for you living with an adult son who has his GF who also has her sister over a lot. There can only be one Queen Bee in a house so these problems will continue happening until one of the parties claims their independence. The whole scene is very weird - how can a man poop when she's in the tub and how can she stand the aroma and acoustics (trying to be delicate here). In any event it certainly wasn't a romantic setting.
