Girl pleasing girl

HIiii. Okay, so I’m sorry if this comes off as ignorant. But I’m genuinely curious. I have a huge crush on a girl and she expressed liking me too both sexually and romantically. It’s very new. I’ve only liked boys before. So now I’m wondering how can a girl please a girl sexually? I get clitoral stimulation and head, but what if I require penetration to come? Are dildos as good as penises? I’m attracted to this girl but don’t know how we could possibly make it work sexually. I want to kiss her and cuddle. But I still think I need real dick. Am I heterosexual and only biromantic?
