Is it weird that my best friend and i hump each other?

my best friend and I have been friends for about 4 years. One day, she turned to me and asked if I was straight. And I said idk, I think I'm bi. So she asked if it would be weird if we kissed. I said no and we started making out. While we were having a sleepover one day, she leaned in to kiss me and then I rolled on top of her. It felt, good. And so we started humping and kissing and then she put her hand down my pants and she paused and asked if I was okay. I said it was fine and she pushed me onto my back and straddled me. She started humping me now and with her hand still in my pants, started to finger me. She's was moaning now and she guided my hand down her panties and I knew what she wanted. I felt her starting to cum and that's when we stopped. We thought it was enough. But then, about 20 minutes later, she asked if I had even seen porn. I said no and asked her if she had. She said no but she kinda wanted to. So, we turned on porn. We watched lesbian and straight. Is that, bad to do what we did? We still do. All the times we hang out.
