Is it normal that me and my friend fingered each other?

Okay so me and my friend were in her pool at like 10 at night so it was dark. She asked if I ever had gone skinny dipping. I said no and asked if she had either. She said sort of. So I said let's do it. We knew her parents would potentially see us so we went to the side of the pool that her parents would have the least view of us and put a rubber floating thing on top so we could breath and everything but it was covering us. We took our swim suit bottoms off to our knees and moved our bikini tops to our stomachs exposing our boobs. It felt really funny and cool. She said 'let's play a game where you say boobs, butt, or vagina and then the other person sucks/licks and touches/rubs that area.' I'm pretty sure I said vagina first. So she started rubbing my vagina and tried to put a finger in there but I asked her to stop cuz it hurt. Other than that it felt amazing. The licking part for vagina was a little weird. We didn't really want to lick each other down there so we just kissed each other's vaginas. It started as just that but we got really horny and started to make out. I was getting so horny so I asked if I could grind on her knee I know lol. Then a few weeks later she came over to my house and we had more sex on my bed. It started out with just dry humping but I really liked it so we took our clothes off and scissored and fingered and had pretty rough sex lol. It's weird cause I don't feel attracted to girls at all. I think I just feel more comfortable doing it with a girl cause I'm closer to them. I don't find girls attracted at all. I don't get a tingly feeling in my pants or whatever. I get turned on by hot guys.
