Sex Doesn't Guarantee Wisdom

I was a bible study a couple of weeks ago and something that the leader said really stood out to me
"Age doesn't guarantee wisdom"
It just made so much sense. I wrote it down, and stored it in my mind.
I wish people could realize that sex doesn't guarantee wisdom either.
I hate how people think that sex will open up all this knowledge of life to you and somehow transform you into a mature, real, human being. Am I the only one who thinks this is absolute madness?? How is having sex supposed to affect you as a person in completely unrelated ways? How much more are you really going to know after it happens? It's not like afterward, every life question is answered and you finally know everything. Sure you will experience new things physically and emotionally but they really don't go outside the the category of sex and human interaction.
I guess the reason why I am bringing this up is because as soon as anyone hears I am a virgin, they instantly assume I am pure and innocent and naive or some shit like that. I am not stupid or prude, I am perfectly aware of what sex is and I like that I have chosen not to have it at this point in my life! Seriously people, I like to drink my weight in vodka yet being a virgin makes me angelic? wtf???
Why does the fact that I have never done it effect people's opinions of me? I have been told that I am a generally nice person, I've also been called sweet, but I like to think that it is because that is just who I am and that those opinions wouldn't change if I wasn't a virgin.
Also, the fact that I am a virgin doesn't mean that I am dumb enough to believe everything a guy tells me, I know the kinds of things they will say to get in my pants. Just because they haven't succeeded in doing so doesn't mean they haven't tried.
Is it weird of me to think that virgins can be just as guy-savvy as non-virgins? is that just idealistic thinking?
On another note, how come girls seem to segregate and judge each other based on the virgin thing? why does that have to matter so much? Sometimes I feel like virgins think that non-virgins are sluts (regardless of the number of partners or sexual encounters) and non-virgins think that virgins are little girls.
Doesn't make any sense to me whatsoever.
