I use to not be able to tell when my DH ejaculates inside me however i have noticed after really paying attention to our bodies while where doin the deed that right before he ejaculates his member becomes more hard and the head gets slightly biggger. also it seems that right after he comes in me. sorry (TMI). my cervix seems to contract. i konw they say having sex is a way to induce labor because there is a component in Sperm that makes the uterus contract and this may help jump start laber.
I agree with cnj76, I don't ever "feel" the ejaculate being released either. I have always had "leftovers" that came back out. Some immediately and some the next day. But, in 12 years my husband has gotten me pregnant 7 times so it's obviously not hindering anything :)
I never feel when my DH ejaculates. Only by him saying so or obvious ways of him letting me know that he did.. Sperm is deposited at or near the cervix and what usually comes out is mucus. Think of it as gravity, what goes up... must come down. If you are trying to get pregnant.. Lie flat in bed with a pillow under your hips if you are worried that it's all coming out. But, it happens to us all. Good luck :)
well...i don't ALWAYS feel when my SO ejaculates. usually only in the rear-entry position. as for the part of it "blowing back" on him, while he may have quite a bit on him, you have to remember, while when he ejaculates, it does "blow". but not straight up in a line. so unless he literally "blows" and backs out in the same stroke, he's going to have some on him. and honestly, i've never heard of a way to keep that from happening. if you're TTC, i suggest elevating your hips during sex, like placing a pillow under your hips, if it's comfortable for you, as well as leaving that pillow there, and lifting your legs afterward to help the sperm make it's way towards it's final destination :)
