I'm a straight guy married to a wonderful woman. She has a daughter. This girl's bio dad is a checked-out deadbeat, so I have played "dad" since I met her mom five years ago. The girl who used to be a gangly, awkward 11-year-old is now 16, and there's no other way to put this: She is hot. I'm not supposed to notice, I know, and I have ZERO interest in being creepy with her, and she has ZERO interest in me. But she has always liked to cuddle with me and still does. I believe safe closeness from a dad figure helps girls make good choices when it comes to boys. (If not for me, she might seek attention from douchebag teenage boys trying to take advantage.) I want to continue to play this role for her. But when she comes in wearing tiny shorts and puts her legs over my lap, I get rock hard. I'm not trying to be creepy, but I'm a guy and she's a perfect female specimen. I can't say, "We can't be as physically close as we used to be," because that itself would be creepy and it would make her sad.
