me and my boyfriend used to stay up late every night untill like 4 in the morning watching dvd's when we would watch the last dvd that would be when we had sex. we used to have sex everynight around that time. but recently he has totally lost interest in sex. i worry that its something to do with me, wether hes not attracted to me, or if im not doing something right. im quite a shy person, so i tend not to ask him about it. but on the odd occasion when i do ask him, he says its because hes tired from work and gets moody with me. we argue a lot more recently too, could this be because we dont have sex? my best friend and i spoke about the sex 'issue' and she said sex is very important in a relationship, and i agree. i dont feel wanted anymore, i need help!!! and fast. x
