John & Emily, separate rooms may or may not be a mistake for you.
For your first experience, the sight and sounds of your spouse as they mate with someone else can be a tremendously erotic event, to be relived over and over as you recall the loss of your monogamous 'virginity.' In addition, the wife often is a bit nervous, that her husband is so close can calm her, help her to feel more safe.
On the other hand, the thought and sight of his wife with another man can often give a newbie husband ED; sometimes (but not always,) being away from her allows him to concentrate on the woman he's with and respond to her better. Also if there is jealousy on either's part, it can sometimes be better handled.
Either way can be a perfect time, or it may in retrospect, be a 'mistake.'
