I could have written that exact same post while TTC Olivia. We lost all the passion and it got so bad that DH couldn't even come because of how unromatic it was and the pressure we put on ourselves. We were only doing it missionary with a pillow angling my pelvis up for minimal spillage, I was temping and charting, watching my CM and cervic position and texture and using OPK and we would do it every second day except the five days leading up to ovulation it would be every day whether we 'felt' like it or not. No wonder we couldn't conceive. In august last year we just forgot about everything and went back our old sex life. DTD in all positons, with toys, sexy lingerie and everywhere around the house and just brought back the fun and along she came. We kept telling each other to relax but how could we with the stressful/routine we had put on ourselve. It was horrible.
Go back to having fun and enjoy be so initimate with each other on such an amazing special level and hopefully the love you express for each other will bring another baby into your life.
Enjoy DTD!!!
