What luck to have you turn up like this at this time! I've got a large project, but this is very much a small part of my goals, so I'm happy to help you along.
The log format is great, but I really must ask that you post updates here - Google Docs is just a pain in the ass sometimes. In fact, please copy and paste everything from that document here - I only see a blank page.
On to the topic… why would you have any problem with armpits? After all, a good whiff of your lover's armpits simply gives you your lover's pheromones, which should only make you more aroused. And they're right there so close that you get the pheromones as you go in for a kiss… mmmmmm.
You're better off avoiding deodorant anyway and simply washing your armpits thoroughly with soap when you bathe. If you bathe before bed, spray or wipe your armpits with a little bit of rubbing alcohol when you get up. A spray bottle works better if you choose to grow armpit hair, wiping is easier if your armpits are smooth. The offensive odors are bacterial waste products. Your actual scent is a bit different and quite interesting. I look forward to reading your description of how your own body smells. ** ** :-)
Deodorant is both nasty and a major bitch to get rid of, even after you stop using it entirely. I stopped using it when I got tired of it caking in my pajamas and turning my bed clothes all nasty. Then I washed my pajamas, scrubbed my armpits - and there was still nasty deodorant crud coming off because it was stuck caked into my armpit hair. Ick. You'll need to shave your armpits and any nearby body hair and scrub those areas throughly with soap and water in the shower every day for at least a week. You'll need a mesh bath sponge - washcloths are simply too soft. You should only need to shave once if you don't relapse. After that, you can choose to grow your armpit hair or keep it trimmed.
You'll be amazed how sexy your own body can smell and it will really boost your confidence when other people start responding to your pheromones. Just be sure to be a good tease for them - if you're the only one without deodorant, you'll be the only woman who actually smells like a woman. Enjoy the attention you'll get - and do tell us the stories!
