Concentrate more on your nipples. If you can, lick and/or suck on your nipples. That should help.
I may not be able to answer this question from experience, for I am not a female, but i would say no. You do not need to be embarrassed about it. I am openly pan, and have had no problems with it, nor have other people. If girls are your gig, then go for it. You should not be embarrassed about the way you truly feel.
Yes, don't be embarrased to be female, your nipples are part of you. If they stick through your shirt it is part of life, as long as you are comfortable. You could try a more padded bra, but be comfortable. Don't be embarrassed, alot of gals try to have your look.
It depends on what you meant by dirty underwear. If you've made love and may have some spotting from a period, then no, you should not be embarrassed. Young men know about those things. If you are not practicing good hygiene then yes, you should be embarrassed and it's a signal for you to practice good hygiene. Good job Marcy. Girls typically get embarrassed too much for no reason.
