From what i understood, and i could have misunderstood, you BD and afterwards, before you get up, you put the instead cup in to KEEP it all up there, kwim? So he needn't deposit in the cup and you needn't try and manoeuvre it up to your cervix without spilling any.

You could BD, lie together a while, then lift your hips and insert the instead, lie a bit longer, then get up? Would that work out?

Could be wrong about it though..? Anyone else know?
