Answer:
If it's not safe to come out (as in, if you're at risk of getting kicked out or abused) then, despite you wanting to, I sincerely think you shouldn't. (This is if you live with your dad) If you don't live with your dad then it would be safer to come out to him, unless he's verbally abusive; in that case, it's best not to. Now, if it is safe to come out, then I suggest you just take a minute to tell him, preferably at night because people are more emotional, vulnerable and accepting then. You can also leave a note or letter if confrontation is difficult for you. If you aren't sure if it is safe or not, try to drop small hints until you're sure.
Explanation:
If you come out to him, I hope it goes well :)
