<human>: Throwaway, plus I'll try to keep it short.  Anyone with a similar experience please comment.  
We've been married for almost 13 years and have gone through many ups and downs and have a few kids.  Things are better now than they ever have been.  We are getting along, finances are good and the sex is more frequent than it ever has been, partially due to a near divorce fight earlier this year that made us face that we love each other and decide to stay together.  Since then everything has been moving in the right direction, except one thing.  
While I stated the sex is much more frequent, which has helped me immensely, it tends to be pretty routine and sometimes almost awkward.  She rarely dresses up for me though she owns lingerie, she always needs the lights out and wants the covers on, she often just wants to be missionary, and sometimes she's downright a control freak about what and where I am allowed to touch, kiss, etc.  She is often childish, wanting to giggle about stuff and it really can be a turn off as I want to be with a woman, not a girl.  She brushes me off when I look at her with lust in the day to day routines (downblouse, bending over etc) when I would like some playful acknowledgement or return.   In some cases we have actually regressed sexually.  She no longer will let me go down on her, though she will for me from time to time, and she used to like it.
What I need help with is this: I don't need a sexual acrobat in the bedroom, but after this many years, the extra few pounds we carry shouldn't matter in the light of the fact that I am wholly committed to her and I adore her body because it is mine.  Except when it isn't.  How can I gingerly ask her for a more adventurous and varied ADULT bedroom without hurting her feelings?  
Just to be clear, I'm not asking for straps and leather or voyeurism or anything freaky at all.  I just want to feel like our sex life is progressing in style and quality to go with the frequency.

Can you give me a shortened version of the text?
<bot>: Our bedroom is busy, but mostly routine and sometimes childish and I'm looking for help in how to move our sexual relationship forward.
