Insensitive...and I'm not talkin emotions

Soooo I've been sexually active for just over a year now...and I've never achieved orgasm and I've never came...I've tried everything. My SO has tried everything.... It's like I'm not very sensitive down there. Like I get super turned on and horny at just the sight of my man and then things that are supposed to be pleasurable really don't feel like anything.... I'm almost 20, I'm young, and I don't feel like this is normal at all. It's seriously starting to depress me because I don't feel like it's normal, and obviously my boyfriend feels like he isn't doing his job, but I know it's something going on with me. Is this something I should talk to my doctor about? Any advice would be truly appreciated!
