Can I shrink my large nipples?

I am an eighteen-year-old male and I have had an embarrassing problem my entire life. My nipples are rather large and round. I'm not fat, and the rest of my body looks normal, but my nipples protrude and look very strange. I have spent much time doing every chest exercise imaginable, and although my chest muscles seem to grow, my nipples just get pushed out further. This has been a source of insecurity for me for a very long time. I am ashamed to take off my shirt in front of others. I really think that my nipples are the only thing keeping me from having a nice body. Is there anything that can be done to correct this problem?


Is there a connection between emotions and physical pain?

When I hear someone make a negative comment about me it sometimes sticks and for some reason my chest will begin to hurt. A friend of mine said it was emotional shock. For a while the feeling went away, but then it got worse. Now the pain will range from my heart to my left arm, depending on how badly (depressed) I feel. In general, I want to know if I should be concerned or if it's just as my friend says: "emotional shock," that's just gotten worse.


Why are my nipples hard?

Is there a reason behind spontaneous nipple hard-ons? Lately one of my nipples just stays that way for the majority of the day. It's irritating! Is there a reason behind it?
