I don't think you are confused based on your views so far. You are just not sure whether to come out or not and here are things to consider strongly before you do that. 

1. Overall personal happiness is the goal of your life and choose the paths that you think will make you the most happy. 
2. As you mentioned in one of your posts, out of 24 hr clock, you are probably going spend fraction of time as gay(sexually) but as an an gay individual at other times. (Consider how that will impact yourlife and happiness)
3.Consider how important your friends and families are for your life and happiness. You can choose your friends but not your parents or relatives or siblings so take this issue seriously for your persuit of happiness.
4. Consider the age you will go through 20, 30, 40, 50, 60, 70, 80 - how important is it to be gay in all these years for you to be happy. At old ages other things might be more important for you to be happy than your sexual identity. So consider all aspects. Once you come out there is no turning back, at least with the society and the view we have at present.
5. Consider your job, residence (current and future) and make sure you wont have to compromise too much.
6. Alternatievely you could practice gay sexuality without coming out and come out later totally or go back to being straight again or stay the same, whaterver works for you.

Again, think long term and consider all the factors that are important for you to be happy
