swallowing sperm is harm less
Your body has no idea who you had sex with before and now. No man can claim you and have your body only be for him and have another man's sperm cause problems in your body. Often do you get a odor after sex, it's normal.
sperm cell
No. Sperm can be present in fluids released before ejaculation.
There is no research evidence that the sperm of a man who drinks alcohol is adversely effected in any way.
It doesn't depend on how much of sperm is produced for a man to be fertile but it depends on the quality of the sperm. Many lifestyle factors affect the quality of sperm, eg. Smoking, excessive alcohol intake , temperature at which the testicles are kept at, etc.
semen, cum, man juice (LOL), and yogurt are the common ones
Its called premature sperm. Its when a man releases sperm earlier than the woman during sexual intercourse.
Condoms don't prevent pregnancy by killing sperm, they prevent pregnancy by capturing sperm cells when the man ejaculates. Once a man ejaculates in a woman's vagina without a condom there is nothing a condom can retroactively do to prevent pregnancy. Best to put on a condom before intercourse. If you have ejaculated in a woman the best way to prevent pregnancy is the "morning after pill". It's a dose of hormones that can prevent ovulation.
I could not find a precedent to Medgar Evers' quote, "You can kill a man, but you can't kill an idea."
A man that has had a vasectomy does not release sperm, however, he does ejaculate.
If it's from a trans sexual born a man before the operation yes it is. Then he has the body of a normal man. If it's a woman after surgery to become a man, not it's not.
