How would you feel? (from a teenagers point of view)

[jaspen]

I wouldn't expect a good response. If Ds and DS GF have established their private time within the confines of his room and you are suggesting to take that away from them indefinitely I'd expect all hell to break loose especially if there is already some tension there. I'm not saying don't discuss it and gauge a response or even not to do it (your familys house your familys rules and what is best for the entire family is what I'd have to go with at the end of the day rather than solely whether or not an 18 yr old will like losing private time with his girlfriend) - but I'd be surprised if it was well received - only you know your son and his maturity though and how he's likely to feel about things like this.
