Help, my b/f asked me to look in the bowl after he finished?

Ever since I started dating this guy, it has been the greatest. We were actually going to get married, we have been dating for over 3 weeks. Well, either way, last night, he called me into the bathroom. I thought that maybe he needed help finding something, but he actually wanted me to look in the bowl. I was sickened by the whole experience, becauce that is nothing I wanted to see. I just immediately flushed and told him I had to go to the store. I just wanted to get out of that apartment as fast as I could. He told me that we should be comfortable with stuff like that because we are going to get married. To make matter worse, when I did the laundry this morning, he had left a pair of his underwear in my dirty laundry basket and it had a skid mark. Is it normal to get cold feet before you get married, especially after seeing things like this? This is not romantic at all. I want romance.
