It is possible to get pregnant by having sex in water. If you don’t wear a condom and use internal ejaculation during sex, it is possible to get pregnant if any sperm enters the woman’s vagina, no matter what kind of water it is in, because the outside water doesn’t intervene in the internal vaginal environment. And the likelihood of condom dislodgement is greatly increased when having sex in water. Hot water, chlorine ions in the water, or oily substances (such as shower gel) can weaken condoms. If any water gets into the gap between the condom and the penis, the condom is likely to be washed away completely unnoticed, so you need to be careful about having sex in water!
