I am just as bad, especially before making love to my husband. If I do not brush my teeth, use mouthwash, clean myself "down there", put on fresh deodorant (and on and on and on), I cannot even focus on what we're doing. However, mine stems from sensory issues with odor. It is actually the smell of my husband that attracts me.
I have been getting therapy and researching smells. So you know, I have learned that, when you are fully clothed and bathe regularly, no one can smell anything around your bottom. Also, if you bathe at least every other day, when you do make love, the only smell he'll catch is your pheremones, which are there specifically to turn him on. If you bathe too much, and scrub too much, you will not only remove that smell, but cause infections.
Find a way to overcome this. Seek counseling and do research. I understand how hard it is. Good luck hon.
