Warning: Sweaty Sex Can Give You An STF

My guy is always in the mood after a gym session. Is it safe to hook up when he's all sweaty, including down there?

Male sex hormones often surge after exercise, and the same is true for you, so take advantage of the moment. Sweat itself doesn't raise your risk for infection, and sweaty romps can be arousing and erotic.

However, men who work out a lot are more likely to get jock itch, an infection (usually caused by the same fungus responsible for athlete's foot) that thrives in moist places—like gym shorts. It affects your guy's groin, so there's a small risk the fungus can be transmitted to you during intercourse. If he has it (he'll likely notice a rash), abstain from sex until he treats it.
