Jen, your nips became more sensitive b/c you are PREGGO...Woohoo!!
About the blog... you know I was thinking about this a couple of weeks ago as Matthew was nursing and thinking hmm, it's kind of odd how boobs are such a big part of foreplay and sexual, yet when he nurses I don't get any kind of sexual feelings, and that's kind of strange if you think about it. I guess because they are being used for a different function? But I can see biologically how it can happen while nursing. I'm sure that is a tough position to be in and kinda make you feel like you've got an Oedipus complex or something.
I've been laughing my head off at Matthew lately because he will pull back, smile this HUGE grin at me and start slowly licking my nipple. It is so hilarious. Between that and Dh placing his hands on my boobs and having him "cop a feel", he is going to be a boob man.
