I personally don't feel like this is TMI but ya never know!
I started to notice a difference in what happens after BD depends on if I orgasm (which I will now refer to as O). It seems that if I O right before or at the same time DH does very little to nothing comes out when I get up. However, if I do not O then it barely takes him pulling out or me moving slightly and then there's a mess. So I've started to wonder if the muscle contractions help with TTC. Anyone know anything about this? Just curious!
