Underwater sex - whether in the pool, hot tub, ocean, lake, river, shower, or bath - isn’t considered a safer sex option. Here’s why:

1. Spermicide is likely to “wash off” or wash away in water.
2. Water containing chemicals, salt, or bacteria can be forced into the vagina or rectum during sex, possibly causing irritation, infection, or temporary dryness.
3. Since it’s recommended to store latex condoms away from direct sunlight, it’s possible that heated water may have a similar effect on latex.
4. Water can seep between the condom and the penis, possibly causing the condom to slip off.
5. Oil-based products - such as sun block, tanning lotion, shampoo, conditioner, and soap - and possibly even chlorine cause latex condoms to deteriorate.
6. Condoms aren’t typically tested in pools or hot tubs, or with chemicals found in these hot, wet places. Of course, using a condom in a pool or hot tub is better than not using one at all.
