Take heart gvenkat, there's not too much you can do "wrong"
Most of the seamen ejaculated during sex comes out again anyways. Luckily, it only takes one to fertilise the ova.
I wouldn't worry too much about the foreskin issue, as long as some seamen ends up on the inside, I'm sure 1 little guy will find his way!
You might like to try lying down on your back for a while after sex, and even elevating your hips with a cusion or pillow, to give those little spermies a good chance to make their way to where the action is.
good Luck- we're trying two, also, on month two (although I never count the 1st month off the pill as really official trying)
