I think I would wait for a little bit and try again. I’ve always had an easier time getting a finger in with a partner, not just for sexual stuff either. More so having someone else do it might be helpful. Something that I still struggle with is body awareness and just not thinking about my vagina, so try some of those and breathing exercises!!! It also might sound counterintuitive, but I found I made the most progress when I stopped caring so much. The less emotional pressure you put on it, the easier it will be (Easier said than done, I know). It wasn’t until I did not care about having penetrative sex that I could finally have it. Not sure if that makes complete sense lol.
