would be funny if i were talking about you x) so i was in the bus the other day and saw this girl with like the hairiest armpits ever i was like wtf and thoought eww what if i look like tht?!! so how probable is it tht my armpits get hairy and nasty? i'm18 and my armpits have nothing at all, they soft and nice n.n also,they say tht armpits smell bad, mine, i personally don't think they smell at all! i might be nasty but i jlike how they smell cause i have bb lotion all over my body all the time x) so yea will i ever get hairy armpits why donnt i have them, is there more ppl like me and is it ok if i think my armpits smell good?
