i'd say stop shaving your arms lol.... i don't think ther's any guy that really finds that a turn off... armpit hair yeah, leg hair hair, yeah, no one wants to see robin williams in a skirt... but arm hair is fine... i actually find it kinda attractive... not like deep black facial hair type arms, but the soft gentle peach fuzz...

as for the mole, i'd call up a doctor. fucking with moles can cause cancer.... not all moles are cancerous tho...
