HAIR, help

so I have this issue where I grow lots of hair in odd places like my chest, nipples, and stomach. I've had this problem for a long time and I need help! Anyone have the same problem or know a solution? I've been doing Nair and shaving my stomach but it comes back too coarse and fast :( please I'm afraid of what my boyfriend will think so we have sex with my shirt on and he always asks why I won't let him see me.
