I had my first sexual experience with a girl at age 7, could this have started problems?

The babysitter I stayed with had a neice. She dragged me into this game called "privacy parts." Basically, every afternoon, the babysitter made us nap in the same bed. The girl and I then felt each others boobs touch each others genitals, It was the greatest rush of my live. Problem was, that my sister hid in the closet while we "played" Then at home she became apart of it. We didn't know any better. Could this have contributed to sexual problems in the past, like porn addiction or webcam sex? I started masturbating almost immediately after "privacy parts."
