[MF] Fingered a girl

Hi, I would like to share my story and this is my first post ever written. English is not my native language and I apologize for mistakes in advance.

I met my wife when I was 19 and I am 30 now. I had been only with one girl before meeting here. I never cheated on her before this story and never wanted.
A few years ago I had a really hard time in my life. When I say hard I mean really hard, not just standard problems with job or something else. That changed me a lot. I got more passion for life and started thinking about other girls. I was curious to try different things with different women. I didn’t want any relationship, just wanted to know how other girls kiss, how they moan, what they like, spank different ass, get different blowjob… As I said I never wanted to cheat and lie to my wife. She is a beautiful person and I didn’t want to hurt her. The idea to meet a girl and come back home after her was disgusting for me.
