Re: Just a question?
Sperm are constantly being made and replenished after every "use". Any sperm that are damaged due to heat or cold will be replaced. In years passed, it was believed that if men sat in hot water, they would be infertile and safe to have sex with...Well, as with all old wives tales, it turned out not to be true.
Men are capable of producing millions of sperm every day, and as long as his sperm are viable, he should not have any worries about a little hot tubbing or swimming, as long it is is relaxing and fun while he is doing it.
Best of luck to you...
