Only the first sperm influences what happens so it is physically impossible.
I would recommend ejecting sperm in women not men.
Nearly all men make sperm, which is what makes a woman pregnant. Men transfer sperm to the woman by sexual intercourse - the whole process is natural and does not need medicine. For the very few men who do not produce live sperm, the best course is to see a doctor, who will get tests to see if the situation can be improved.
it happens
Nothing.
it's ok to swallow sperm. I do it all the time with black guys. it's better to do it with black guys than white guys because black guys are more tasty than white guys. IF YOU ENJOY IT LIKE ME NEVER STOP DOING IT
most men (mainly straight men) don't like the idea of sperm epically their own and even if you don't swallow after blowing them they mostly wont want to kiss you because of the sperm having been in your mouth.
I can think of three reasons, depending on the man. Some men like the idea that the woman is being submissive. If the man's penis is deep in your mouth, swallowing feels good to the man. If the woman is willing to swallow, it means the man doesn't have to worry about pulling out at the last minute. He can just "go for it."
Its called premature sperm. Its when a man releases sperm earlier than the woman during sexual intercourse.
Women can not produce sperm. Only men can.
Some men experience that sperm self ejaculates usually whilst sleeping. The rest is absorbed into the system and removed. Sperm is being produced and renewed constantly.
girls are actually easier to conceive than boys. girl sperm are generally stronger. sperm counts lessen in men with heat, so tight underwear for men, position; woman on top,
