Affection

I've been told by many, though I'm a nice person, I'm not an affectionate person.  I realize this as well and I don't see anything wrong with it.  To me, affection makes one vulnerable.  Why give my love to someone I barely know? Why share intimate moments with someone who may turn around and leave?  I don't like hugs, I don't like kissing, I definitely don't like cuddling, and sometimes I am even skeptical of alone time with a man.  I believe getting to know someone before you share any type of intimacy (friendly or romantic) is important.
