I can't answer much of that as my LO is almost a year old and AF is still gone. But I knwo the first few times (like a handful of times? ) it did hurt to dtd...but it eventually gets back to normal, at least it always has for me.
I rarely am "horny" LOL....but will decide it's been long enough! ROFL...so I make myself in the mood...works for us..he knows nothing different and so he doens't feel bad or neglected or like I dont want him lol....
GOOD LUCK TTC! We are in the same boat...not preventing...but not trying....ideally I'd not get pregnant for another 6 months at least but will welcome it before then!
