My boyfriend and I are both 19 years old and have been together for a year and a half. We are both students at the same university and do a lot of work during the school semesters. We have had a lot of issues from the beginning of our relationship that we have tried to work out i.e his ex girlfriend and my self esteem. Now sex has always been really good for both of us. During the year it is a little harder to do it all the time but we still did it a few times a week. Then as the months went on our relationship has hit rock bottom a few times but we really care about each other so we try to work it out. All of a sudden though my boyfriend decides that sex isn't important to him anymore and that little things like seeing me smile and what not, which are great, make him happy. I told him to talk to me and to open up and that this was never going to work if he wasn't honest with me. He said he was not cheating and that he is used to not having sex and that it just isn't important to him. This is really killing me because my self esteem is low to begin with and this just isn't helping. I just really think this is weird that a 19 year old doesn't want to have sex often. I need advise!!!
