“Hello, Thanks for your advices, you wrote well.
But please if we don’t douche after having our vagina filled with sperm we will smell sperm during hours, how to deal with that when having business days ?
As in other mammals, the human vagina is very good at getting rid of excess sperm, without using a douche. Shortly after sex, much of the semen deposited in a vagina will be expelled – by a process called Flowback.
Flowback is a phenomenon observed in not only humans but in zerbras, mice, and sparrows as well (it probably occurs in all mammals and birds – we all have more in common than you think) : it’s the ejection of leftover semen from the vagina - actually most of it, including around 50% of the sperm sent in.
Here’s how it works:
After unprotected sex, the deposited semen undergoes liquifaction.
This liquifaction-ized semen is then expelled from the vagina in one of two ways:
either it drips out slowly into your panties (or down your ass and onto the sheets)
or it shoots out when you pee, sometimes with quite impressive force.
About 15 mins after unprotected ejaculation, the pool of semen left in the vagina, including any sperm not collected by the cervix, becomes more watery (liquifaction) then tiny muscle movements start pushing the semen towards the exit.
It can take from 10 mins to 2 hours for this mixture of semen and vag juices to collect in the vestibule and once it does, a cough, a sneeze, and especially taking a pee will send it flying out of the vagina.
If none of these happen, then after about 2 hours everything becomes so liquidy that it just starts dripping out by itself.
Although this is NOT an effective form of birth control, it can make cleaning up after sex much easier.
But if you are really worried about leaking semen all day after sex (and not catching any nasty diseases), you could also try using a condom.
