No. It's not healthy for the anus to be dilated for that long.
Its how long you have to massage its anus, whilst it tries to give birth.
If there is no egg present in the oviduct when the sperm arrive, the sperm will typically die off and be naturally cleared from the body. They have a limited lifespan and cannot survive for long periods within the female reproductive system without encountering an egg for fertilization.
Sperm cells are small, motile cells with a distinct head and a long tail. They are typically streamlined in shape to aid in swimming towards the egg for fertilization. Under a microscope, sperm cells appear to be oval-shaped with a long, whip-like flagellum.
All animals have an anus because all animals need to defecate.
Sperm that enters the anus during sexual activity typically does not survive and cannot fertilize an egg, as the environment is not conducive to sperm survival and transport. The digestive system and immune response in the anal region would not support the survival of sperm cells.
Inside of another mans' anus is preferred.
Pregnancy can only occur if sperm fertilizes an egg in the uterus. The anus is not connected to the reproductive organs where fertilization takes place, so it is not possible to get pregnant from anal intercourse.
unless your partners allergic to sperm, then no.
The human anus is not designed to hold sperm; its primary function is for the elimination of waste. However, if sperm is introduced into the rectum, it could theoretically be retained temporarily, but the amount would vary greatly depending on individual anatomy and the position of the body. Generally, any sperm present would likely be expelled shortly after introduction. It's important to remember that the anus is not a reproductive organ, and such practices carry risks, including the potential for infection.
Sperm entering the body through the anal passage does not result in pregnancy, as the anus is not connected to the reproductive organs needed for fertilization. However, there is a risk of sexually transmitted infections if proper protection is not used.
