When is coming out a good time?

A little background info: I'm 19, I have a job, and have been in a relationship with my boyfriend for 10 months. I love him to death. He's completely out, and I'm not out at all. Just mutual friends between me and my boyfriend and his parents know. My parents are, for a lack of better way to explain, 70% against LGBTQ+ and 30% for it. My mom has openly expressed homophobia, but never really took it "too far". I really want to come out so I can bring my boyfriend farther into my life and stop worrying so much about who knows and who doesn't. People say, "wait for whenever YOU think it's right" but honestly, I don't even know when that is.
