So I am a little embarrased about this... I have a very beautiful step sister and since she was 15 (she is 18 now, and I am 23.) I have been in love with her and it's sort of an infatuation. I have often fantasized about her while making love to my wife and other girls. And everytime I tell her I love her I mean it more than if I was saying to a sister. My question is is this normal? When I was back home I asked her that if me an her were not related by marriage and she had met me elsewhere if she would have dated me she actually said yes, much to my surprise... me and her have always had a very close relationship and have always talked about things, I think that is where the love comes from. Please tell me I am normal, I always look at it that if her mom wasn't married to my dad it would be normal. The last thing I would ever want to do is hurt my dad though so I could never act or wish them to get divorced. Ty for your time and look forward to hearing from you.
