Once you start Puberty you will begin to have sexual urges and fantasies. This is normal behaviour.
Try masturbating.

No, that does not make you a bad person. Everyone no matter what age thinks abut sex -- I would just like to see anyone deny it. You are not a bad person because thinking about sex and having sex are different things, but still you should not have sex -- you are still too young. It's pretty normal to have an big increase in sexual fantasies and arousal when you are a teenager. Plus you'll (erroneously) believe everyone you know but yourself is having sex, and that you'll never get laid. Believe me, you will--so enjoy your fantasies, view a lot of porn and wait to have sex with someone you're comfortable with, whether it's a couple months or years from now.
I am presuming you have them? Personally, i think it's odd, but if you knew the fantasies i have you'd think im worse.... ANYWAYS... He's your step dad? probably 20 mabey 30 years older? you are just probably attracted to the older, matured, sometimes sexier man. That part is normal..... Let's say you're 16? go have sex with an 17 ALMOST (but not yet) 18 yr old. ( : then, once you are 18 or older you can go up a little more ( ;
yes very normal! lol
As far as psychology is concerned, a teen aged girl of 16 years normally does have occasional wet dreams simply because she is in a puberty stage. This is the point in time wherein active sexual hormones are secreted into the body system. This should not constitute that persons experiencing this should be bothered that they are having so much sexual fantasies and they should repress it. You should take this normally just like everything else.
Why would you be straight again? People don't change from gay to straight and back again, unless they are bisexual. Who are you attracted to? Who do you love? Who are your sexual fantasies about? That should give you some answer to your question.

There is nothing illegal about dating. Having actual sexual intercourse may be illegal in some jurisdictions - depending on the age of consent, which usually seems to be either 16 years (in some jurisdisctions) or 18 years (in others). If you are planning on having sexual intercourse, check the laws for your country or state/province.
yes this is very normal when you get older you start to get interested about sex and you want to look it up.
I have never heard of someone having braces for that long. If it is nessecary, then I don't see why you couldn't have braces on for that long. Is it normal? Not really. Is it nessecary? It might be.
