Hairy armpit.... i hate it and find it unattractive and a big turn off. Thats just me, well not just me but i can speak for the rest of my freinds.All models i've seen have shaved armpits so i guess there most be something about having a shaved armpit but imagine having a girl in a cocktail dress and doing the salsa and when you look she has two afro under her armpits. Ewwwww and for personal hygiene it keeps your armpits cleaner. The mole will be ok just make sure its not infected and being shaved will help.
