No oral for me:(

Ok so much husband and I have been together for 4 years and he's seiously.only gone down on me 3 times... total. I've never been with a guy that I even have to ask for it.... I've said something about it to him b4 and he says he just doesn't care for it. But I miss it sooooooo much. I mean he uses a vibrator on my alot but it's just not the same and now I think like is there something wrong with me??? I'm very self conscious about it. Anyone else have this problem???
