More information than I thought I would ever give on HN, but I rarely use antibacterial soap on my entire body (I do shower daily). My wife finds it completely perplexing that I exhibit no body odor at most times, even when sweating heavily.
"East Asians have fewer such glands than Europeans and people of Sub-Saharan African descent, which decreases their susceptibility to body odor.[28][30] Individuals of Sub-Saharan African ancestry have the largest and most active apocrine glands.[31] Racial differences also exist in the cerumen glands: apocrine sweat glands which produce earwax.[3] East Asians have predominantly dry earwax, as opposed to sticky; the gene encoding for this is strongly linked to reduced body odor, whereas those with wet, sticky earwax (Europeans and Africans) are prone to more body odor.[32]"
Why would your SO be frustrated by minimal BO on your part?
Jealousy !
Furthermore, to quote a microbiologist friend, an antibacterial soap that kill 99.9% of bacteria (assuming you take the percentage at face value) will just result in the remaining bacteria dividing until your skin has returned to stasis of the microorganisms living there in just a few hours.
Use a normal soap. Wash your hands. Don't freak out about it.
