" i could have sex but it is a lots of sperms come out from me"
It sounds like after you have sex and your partner ejaculates the semen then discharges from your vagina. Sperm leakage from the vagina is normal!
Probably you mean you are squirting. Some woman discharges after sex. It is not semen. Many woman enjoy squirting. Google squirting by women and learn the details.
You're a woman in your 40s. You should know that women don't produce sperm. Only men produce sperm. Women have eggs. When a sperm from a man is propelled inside a woman's vagina and it meets a woman's egg, that is how conception occurs. Nine months later a baby is born. That's how it works. Bottom line is, you don't have any sperm so it wouldn't be coming out from your body.
