Is this weird?

My bf (29, male) doesn't have that high of a sex drive. This has always been true, so that part isn't weird. It's just how he handles it sometimes imo. I (24, female) have a very high sex drive unfortunately. It drives me nuts because I go back and forth between really wanting him bad to feeling ashamed that I would bring it up when I know it annoys him. I don't want to be pushy, but he could go two months without it and be content. I can't go more than a week without it. Anyhow, we used to flirt quite a bit (sexually and not) and he would always be so willing. Now he's not really. He giggles at me most of the time because he thinks it's cute when I do it but he doesn't really do it back anymore. He still lights up when I do it, but there isn't really any reciprocation. Tonight he wanted a massage because work left him in quite a bit of pain so I happily gave him one. I flirted with him then, too and moaned in his ear and all that because he normally likes that. At least I think he does because he says he likes it. Earlier in the day we were texting while he was at work and he sounded like he wanted to hang out and maybe have sex because we haven't gotten to spend a lot of time together lately. I tell him he's irresistible all the time and I did when he got home and when I asked him if he felt the same way there was an awkward silence and he just goes, "Well, I mean, you're attractive." Then he kinda just played videogames until he decided it was time to sleep. He was completely unphased by my flirting and didn't even really hang out with me and I miss him. How should I go about talking about this with him? Am I being a needy little bitch or what?
