never had an orgasm with a guy!!

so I get orgasms every time I'm on my own but with a guy it just never happens. like I'm just never turned on like that but I know I'm sexually attracted to him because I think of him when I'm masturbating and it works fine. however even then it takes too much imagination like I have to masturbate to get wet then to orgasm, I never just get wet without making it happen . do you think I might have a problem with my hormones?
