Ugh sexually frustrated

Been with my husband for almost 4 years and i. Those 4 years we never had a problem with sex . we usually had sex every other day. This is the first time that we haven't had any sexual contact in two weeks ..im extremely horny and I've told him how I felt but we just don't do it. I know he's not seeing anyone. I think he's testosterone levels must be low Jr something because, girls, I've tried everything to turn him on... I feel like a nympho asking him for sex all the time. I look at him and I just wanna eat him up ugh lol
