Is it normal the me and my best friend finger eachother?

Hi,
ok so I am 12 and about a month ago me and my best friend we laying in my bed just talking and chilling like normal and I don't really no how it happened but we were licking eachother and then started making out. We both stopped eachother and said u no I'm totally straight an thts not gonna change. So we continued and we talked about it after and it wasn't akward at all. So 2 weeks later we were making out again and she lifted my shirt and started sucking on my boobs and we both didn't have a problem with it. And then just about a week ago we were at her house just making out again cuz by then it was like a normal thing to us. Then all of a sudden I realised her hand was in my pants and then she started fingering me. And then I fingered her. And then we were both fingering eachother. Is this werid or wrong cuz it's not akward for either of us. And we've both masterbated with each other. But were both straight I have a boyfriend who I'm totally intersted in and she likes guys and were both not even a little intersted in girls. Help?

Relax, you are totally normal. Now I am 14 years old but me and my neighbor (also girl) used to touch each other a lot when we were 7 or 8. We learned to masturbate together. We did it all the time and by age 9 we were really fingering each other.
Then by the time I was 12 and going to sleepovers I fingered with a lot of other girls. It was just part of growing up and exploring our bodies. One sleepover had 8 of us and we spent the whole night touching and fingering.
Even now my neighbor and I do it sometimes when not with our boyfriends. Nothing to feel weird about.

I don't think there is anything wrong or unusual at all about what you are doing.
