31 [F] First time cheating on my husband

Sorry for the quick story, this is all so new to me and had to tell a bigger audience.

I’m married to a wonderful man. He’s dream material. Our sex life is great. But recently, about four months ago, i began getting interested in his friends. One thing led to another and I joined Reddit about a month ago. From there, I enlisted the help of a penpal, who guided me to going after a friend of his.
