no nasty comments please I just need help.

Right I am 16 and happily engaged to a wonderful man. I enjoy the sex and that but a few years ago I started watching lesbian porn and I still do now thinking about girls doing things to me and me doing things to girls. Yeah I have done things with girls twice I licked a girl out and fingerd her (the same girl btw) but I enjoyed it and want to do it again :/ should I? What am I? HELP!!
