Everyone in the Universe knows right from wrong. Don't f**k your stepdaughters, no matter how much they say they want it. In ten years, you'll both hate each other. You can’t pull down your pants and say “Well this is a man’s penis and blah, blah…” so immediately you must say “No, you can’t look at my penis” and then make up something unconvincing about the why and begin to create a taboo around genitalia. What else can you do?

Lastly, a grown man, whether he is 23 or 46, who has sex with a minor is not only a jerk, but a pedophile. Meaning, he's an instant felon. Secondly, a mad who has sex with with someone while living with or being married to another woman is a cheater and a pig. Third, a man who is married to, or living with a woman and has sex with her underaged daughter, is a felon, a cheater AND a pig. As we are toilet training and thus have an open door policy in the bathroom, I usually sit down to pee so as to show her what to do. So far that has enabled us to avoid any explanations as to what’s between my legs and why it is different to her and mum’s. I find it hard to believe that a 16-year-old girl would betray her mother by having any kind of sex with her stepfather. I know most teen girls don't consider blowjobs to be sex, but it is sex, just a different type of sex.If a girl is ready and willing to have sex with her 15 to 18 year old boyfriend, she is ready and willing to have sex with anyone of any age. She said that she is attracted to the step father. The only reason from my perspective is that she felt upset because she felt guilty in helping the stepfather cheat on his wife which is her mom.

UPDATE: I’ve taken all your comments on board. I never really intended to leave the gender explanations this long but after listening to you all I decided that I really needed to get my undies off in the shower and do it soon in the name of body image and most importantly, preventative behaviour. But for him to put you in that kind of situation and ask those questions about your sex life is really not right at all hunny, How many other young women on his travels do you think he may come on to if he did this so easy with you, breaking your mums trust with her daughter, He needs his head read, At this moment he knows why you wont go home Is he worried, well he should be. I love my girl to bits. She's young, she's gorgeous, and I love her like life itself; but I knew, when she said and did the things she did, that it was a temporary thing, that she was going through some bad stuff, that she would get over it. She did. I still have her as a daughter, and to me, that's way more precious than any random f**k.There is no excuse for it: "My daughter seduced him." NOPE. "He was very drunk." NOPE. "I was pushing him away and he was lonely." NOPE.

There is no other way to look at this: Sixteen year old girls, no matter how cunning or smart THER ARE STILL CHILDREN! I lived with a girlfriend who had a very pretty 17 year old girl. Upon first living there, everything was pleasant, but at some point you have to act like the adult in the room and not be the "cool guy dating her mother." I also noticed that one week she'd hate me and the next she'd be my best friend, and that was fine as long as I stayed consistent with my behavior toward her. Then she started the flirting. At first I thought she was just being nice, but then I noticed it became innapropraite. (Lots of hugging and hanging on me) So I went to my girlfriend, her mother, with it. Once my girlfriend mentioned it to her, she denied it, called me a creep and hated me for months. Oh well. I didn't want her hating me, but her behavior wasn't going to continue, or possibly get worse. The best that I have managed to do this week is to make sure that she knows the proper names for the body parts in question which is an excellent start, don’t you think? I have tears in my eyes as I type this. The only thing that guys can do, in this situation, is to hold your girl and let her down in as gentle a way as possible. As for the Ms. Anon 16 year old, what you can do is break up the marriage and tell your mom the truth, or keep the marriage, and make yourself never do this again, and if you can carry this facade, then you must not continue to allow this to happen. If you do, then you are no better than the step-dad that you gave oral to. She has seen me in the shower at times but I usually leave my undies on when she is around and while she knows boys and girls, she has never seen a penis as far as I know.She looks directly at my crotch and before I can react she points her finger and jabs it into the slight protrusion in my wet undies a few times and says “What’s that thing Daddy? I don't think this is statuatory rape, and regardless of whether the stepfather is a horny bastard or not, the missing factor in this is whether Ms. 16 year old anon here went along with it or was she forced into it. I even resorted to walking around the house naked for no reason at all but as that is not what I would normally do, it felt unnatural. All my daughter could say was “daddy needs a shirt”.
