I worry about it too. I have yet to figure out whether it's something that she will become more comfortable with time and is wanting to be able to make herself more comfortable or if she doesn't feel like it, ie not actively working towards pushing her boundaries. Because there's definitely a difference. And given the emotional weight of the relationship, I think there will come a time where I may have to let it go if they just can't open that aspect of the relationship up. But I'm trying to be patient. It's only been four months and she's never done this before. Other than the physical stuff, she's been pretty lax. I try not to think about how hard it would be to have to end it because of that. I'm falling pretty hard for him.
