just one man's point of view but I've been seeing nudity... pretty much my whole life minus a few years when I was old enough to know what was going on but my parents thought I couldn't handle it... that stopped about 12 and as of today I'm a 25 year ago virgin so while it's your business what you feel is okay or not. a boob shot is probably the least of your worries with a m-rated game... which I started playing about 12 too. and no I haven't gone crazy and ruined everyone happy meal yet.
remember despite what fox news wants you to believe bioware doesn't make h games...
p.s. yeah my parents kinda stop caring when I turned 12 
p.p.s. and yes, they really are, even if only on a subconscious level. otherwise what does it matter.
