Welcome to BB baseballwifecathy! You've already received some wonderful advice here about TTC.
I actually just wanted to recommend a book to you (and if you'd like, I can mail it to you! I haven't opened it in a long time!) It's a christian book called 'Intended for Pleasure' and it was written by a christian doctor and his wife, Ed and Gaye Wheat, and its about sexual fulfillment in christian marriage. It may or may not be relevant to you...
As with any book, there are things I take on and things I don't agree with so I just leave them behind. In any case, I found it really interesting, it could be a useful tool for helping you and DH communicate and there's a whole chapter on the pre-orgasmic wife Some tips, anatomy, and most importantly, they relate it back to how God created us.
I'm sorry if this sounds condescending - that's not my intention.
I wish you all the very best. And please let me know if you'd like me to post it to you.
