Should I come out to my parents? ?

It’s your decision on when you want to come out. So if you want to tell them and you’re ready, than I’d say go for it! If you’re just not ready it’s okay to wait.

The only time I would say you should wait is if they are homophobic/transphobic and you are worried of or unsure of how they will respond. Don’t ever put your safety at risk <3. If you think there is any possibility they will hurt you (be it emotional abuse or physical) or any possibility they will disown you/kick you out then wait until you have moved out or have a safety net (ie someone you can stay with if things go bad).

If this isn’t a concern and your parents are accepting of lgbt then you have nothing to worry about. If you aren’t sure then bring up an lgbt topic and see how they respond if they act neutral or positive then I’m sure you’ll be fine. 

Your parents don't want to know.  They'd prefer not to have to think of you as a sexual being.  They've got no interest in it, and they'd prefer to not have to deal with it.  (This is instinctual.  Are YOU interested in THEIR sexual practices?  No, you're not.  They feel the same way about yours.)

So why should you bother them with this?  Do you want more attention from them?  Are you battling them for your independence in other matters and just think this would be a great way to make things more difficult for them?  Confronting them with your sexuality is an inappropriate way to try to shape your relationship with them.

Your sexuality and gender are personal, private matters that you shouldn't share with your classmates, your family, or anybody that you aren't interested in having sex with.  (Except you might share it with a behavioral health specialist or your doctor.)

The concept of "coming out" is a relic of the 20th Century, and lost the last bit of its social significance before 2010.  Today it's only considered "a thing" by middle schoolers.

Coming out is giving yourself a public label. People will define you by that label and expect you to act stereotypically. The more detailed the label, the less flexibility you give. Before you come out to anyone you should be confidant and happy with the label you give yourself. If you are unsure, don't attach a label, don't come out. The other point to consider is whether the person you are telling needs to know. If you are certain your parents will respond well to the news then tell them but if they are likely to react badly, don't, particularly if you are still living at home. Coming out is not compulsory. You do it if and when you need to. Remember, if you tell one person, even in strictest confidence, you are telling the world. Social media makes sure of that.

Why don't you wait until you are able to support yourself?  You shouldn't be having sex until then anyway.  

Everybody has masculine and feminine traits, so I guess that makes us all gender fluid.
