Does sperm travel faster and further in water than just near the vagina not in the vagina?

If you mean like having sex in a pool or tub, from what I've read, the temperature and pH of pool and bath water is wrong for sperm. They die almost immediately if released into water. If released close enough to the vagina, some sperm may still make it into the vagina. Use a condom just to be safe.

The water has an incorrect temp and a wrong pH balance for the sperm life, then the sperm cannot travel or live a second into water.
