I am not quite sure what you mean. The amount of sperm in semen is microscopic.

Can you feel a man ejaculate during anal sex? Probably not. Just like the top of your vagina the rectum does not have a lot of nerve endings. You will probably be able to feel same heat from the ejaculate but even this is doubtful.

It will definitely drip and ooze out and make a considerable mess so you will feel it afterward.

It's much easier for me to feel a man ejaculating when I'm having anal sex. I'm just much more aware the tension in my anus than the mouth of my vagina. I can also feel the warmth of his ejaculation when he cums.

I can feel my bf when he ejaculates inside my vagina and anal..and it also feels warm...~Jenny

I definitely feel a sensation as the semen moves through the penis and a warm feeling as it ejaculates

i like where this is going

last nite was my first time doing anal. wow wat an experience.... definitely gonna do it again...

some people like it some people dont.....i like it but it does hurt me a little because my bf is quite well equipt so i have to tell him to be gentle for a while then after a while its nice
