This is very difficult because it sounds as though you are dependent on your parents to take care of you.
You need to make the best choice for you. Be sure to take into account your safety and ability to live with your parents until you are able to live on your own. Do not come out until you are ready and feel it is safe to do so.
*Always remember to practice safe sex. Even in same sex relationships there is a chance of STI transmission. Use barrier methods like male/female condoms, nitrile/latex gloves, and dental dams.
