What Causes Sensitiveness In The Breast?

Hiya, i dont no if its a common problem, but my boobs crindge me out like i dont like them being touched, they seem very sensitive like even sometimes i lay there and they feel really funny, if i was to touch it or my partner it kinda makes me feel sick, i carnt even feel them to search for lumps it just makes me feel incredibly sick. Is this stupid or would you say there is a problem?
