OK so set the #1 topic aside if you need to, but do it tomorrow night! Or the next night! Point is - don't put it off too long. You will tend to lose ground with a woman by putting things off. Don't lose your forward momentum.
MAKE TIME for the discussion and stick to it!
Now as for your comments about foreplay with her...
Wow. You really do have a long road ahead of you. Given what you've said above, plus what I've read in your other post, plus the fact that you two never kiss each other...wow.
I'm not saying there is no hope. I'm just saying that it seems that your wife is not in touch with herself at all, or that she is totally wired differently than most women.
For this reason, my first suggestion to you is to NEVER read those silly Cosmo mini-articles. They are for the masses. You need to regard yourselves and your sitch as above the masses, ok? Its not that you aren't "normal", its that you are exceptional. Exceptions can be good or bad. Right now, you are experiencing her exception as "bad", but it is not necessarily bad. It just exceptional.
So please don't ever read a Cosmo poll about "what women want". It will only serve to frustrate you even more about your wife's needs and wants, because you wish she would just want what other women want so you could figure it out and give it to her.
As you already know, she is not going to make it that easy for you.
One quick question...do you really passionately love your wife, for who she is, and does the thought of being happily married to her give you warm fuzzies?
This may seem like a total dumb question, but it is going somewhere...
