TTC and embarrassed

Hi, so is it normal when I am actively ttc (1-2 x a day) in my baby-making window to have an odor? We have been trying to conceive for a long time so I refuse to get up for at least 20 minutes afterwards. I am concerned because if I try and get rid of it I could be killing the sperm? I do have to interact in the world and not stay out of public and would like to know what I should do.
