I also went through a stage where I had to track my ovulation and temps for a long time... but frankly baby making becomes a job... there's no real passion "get-lost-in-each-other-real-hot-sex". This can take a toll on us women. It's not only your 'job' to check these things.
1.Try putting a pillow under your bum while being naughty (laying oin your back.)
2.Don't get up afterward... (I know it's messy, but these things are suppoesed to be messy)
3.Tell him to have a COLD shower Before... (this is 'tadpole' excercise)
4.When he goes to sleep at night... NO undies (the constriction adds to the no proper sperm production)
5.Keep track of your diet (for acid levels..., that kill off sprem)
6.Most importantly RELAX!
Try having an evening (or morning whichever the case may be) where you have a glass of wine... or more, relax, have sexy talk, flirty talk, let nature take it's course. Take it slow, don't rush it. Importantly, you have to be able to cm to 'suck in some sperm'.
