Dear Doctor, I am aged 63 years and my wife age is 54 years. We have oral sex on a daily basis which gives us much pleasure, happiness and clear mind. While doing oral sex with my wife, I never wear any type of condom because without condom wearing oral sex gives us more pleasure than condom wearing oral sex. While doing condom less oral sex with my wife, she swallows all my fluid. Does it give hurt to her beautiful body or will any disease enter into her body? Likewise any disease enter into my body while swallowing her fluid during vagina oral sex? Please clear my doubt.
