My name is Sam. About four months ago, my girlfriend and I moved in together and everything was going great. I found a job and we are both working now and going to school. But I have a serious problem, my girlfriend and I went from having sex like once or twice a day to twice in three weeks now. She doesn't seem to be bother by this and she doesn't even want to be intimate at all with me anymore. I really don't understand what happened. It honestly makes me think that maybe she is having sex with someone else because the change was so sudden and radical. Please help before I go crazy. I love her to death but this change really makes me feel insecure and impotent and I don't know how to deal with it. Thanks
