In short...we've been in a relationship for 4 years. It's a good relationship, we love each other. Also, we've lived together for about a year. However, his sex drive has decreased significantly over the past few months. It leaves me feeling undesirable, unattractive, vulnerable, unfeminine, and just sad. When I do try and please him (through oral or sex), it seems like I can't do my job. I feel like I can't please him, and therefore I get more discouraged. It's getting to the point where sex, and thinking about sex, is almost a sad thing for me.
