For me and me, it happens three or four times a night. What's the impact?

Of course it matters. Let me talk about you first. Normal vagina is acidic, while semen is alkaline. If you do it often, it will change the vaginal environment and easily get vaginal inflammation. It will also affect your husband's health, which is not good for the prostate and will lead to kidney deficiency. As the saying goes, twenty-four or five is just every day. Pay attention.
