Short relationship- large step

I'm 14, almost 15. My girlfriend and I have only been dating for two months. It may sound like a very small relationship, but before this we were close friends for a year. It's very serious and we both have gone through things to make us more mature....and just today, she fingered me. It was consentual and I don't regret it personally. But plenty of people are saying it's wrong to do and I should regret it. I'm just asking for some personal opinions. We aren't going much farther!!! So don't worry. It was clean and all...Plus I'm a female so I can't get pregnant from this. If anyone has any support or just personal experiences I'd like to hear it. Thanks!
