Q. Can a woman tell if her man had sex by his nuts? I was told that if a man's nuts are empty that means he had sex. Is that true?
A. I'm sorry to say that short of catching him with his penis in a woman's vagina or DNA testing there's no way to detect infidelity other than by asking him. If asking him isn't an option, or won't give you a conclusive answer, then I think you've just acknowledged the real problem.
