Realised I’m gay - some advice?

So, I (F24) finally figured out I’m gay.I’ve had relationships in the past with men, so people in my life assumed, like I did, I was straight. Now I’m seeing someone and she’s amazing. It happened in the most natural feeling way that it made me realise everything that past relationships were missing. She’s helped me figure out a lot of things about myself and I just need to come out to my friends and family. I was hoping someone on here has been in the same situation - I’m so lucky to have people in my life that won’t have a negative reaction, but it’s a conversation I don’t know how to start.
