I'm worried that I might be heading into sex in a relationship. Me and my boyfriend have been together for two months, and he recently invited me over to his house, saying that his parents won't be at home. I didn't think of it THAT way until a couple of my friends said that he wants sex. They also told me that most couples have sex after about 3-5 months in a relationship. Is this true??? cuz I don't want any kind of sex in this relationship. :\ Help please?
