being a girl myself, if im with someone im close to/having a personal relationship (eg. boyfriend) then its ok, well actually, delve yourself. but if you dont know them and just want to cop a feel?
dont go there, you will get slapped, if they dont slap you, they have no dignity and will most likely sleep with you with a click of your fingers and nerdish charm.
some girls are very weary of them, (i am) and find it quite invading, they need to trust the person first. some treat their boobs almost like their "vajayjay" as i call it ;) and wont show them to anyone till they are ready for sex and even then they may hide them. it can be down to underlying problems if your still geting slapped by your girlfriend for slipping you hand up their top. dont rush it, ask aswell, girls like being asked things.
dont try and go on your own little adventure without her knowing first where your adventuring (unless you planned or in a relationship where you like that)
i know i ranting but alot of guys dont get it.
Phew...
