You shouldn't do anything. If you are skinnier than other girls, their boobs could just be baby fat. Don't even worry about it. A lot of girls don't even get boobs until they are adults. You will develop boobs eventually. Everyone develops at a different rate. And about them being itchy, I guess that's normal if it's really hot and you're sweating a lot that could make them itch.
Jeez. Att-it-ude! I was just making a suggestion that you correct your sentences a bit so I can understand, or others can. But whatever.
Oh my god! This is just one big run-on sentence connected by 'but's. Seriously I can't even read it! D:
Yes, if you love another woman, you are considered lesbian.
When do you suspect you got pregnant? Some of the symptoms don't show up until later on in pregnancy so you might not even be pregnant. I would suggest the first thing you do is take a pregnancy test. You can buy one at a store without anyone knowing. Don't buy a really cheap one though because it could show you the wrong results.
