Teenage pregnancy. Really? When did that become normal? I thought teenagers were meant to be kids, have fun ,*pokes "Kid's these Days"* not be tied down with babies. I think waiting makes sense as 1) You won't be together for a long time/ever 2)You can get heart-broken 3) God knows what's spreading, seriously, it's not with one person but with all the others as well, gross. Besides, it's better to be fresh than raw...
That is all I can say subtlety and without going against the rules which I support :P
It became normal at the beginning of human existence. There is a reason males start producing sperm at the age they do and women can get pregnant at the age they can. In many countries, having children when you are 13 or 14 isn't uncommon.
The second bold sentence sort of disgusts me. You compare virginity to being "fresh"? One, raw isn't the opposite of fresh, just to let you know. Two, going by that logic, all our mothers and fathers are "rotten". They've all had sex, and that's a fact. I'm sure many of them have had multiple partners, depending of course on their circumstances. Saying that someone who isn't a virgin is comparable to them being rotten (you used raw, I just corrected you) is a terrible analogy. Being rotten also seems to be exclusive to the female reproductive organs from what I can see, no? Would you call the penis of a man with multiple sexual partners "rotten"?
Anyways, moving on to my views on this issue, I feel that those who are stable in all the ways necessary to raise a child should be able to have children. I don't find anything wrong with that. I also don't find anything wrong with sex without marriage. Sex is largely a recreational activity in our society, and I defy you to give legitimate proof as to why that is wrong, by legitimate of course I mean proof outside of a holy book.
Pregnancy without marriage also doesn't bother me. Provided, again, that those who are going have the child/raise the child are stable in the necessary ways, I don't see a problem with that. The whole stigma on unmarried people bugs me. As I see it, marriage is a path, but it's not the only path. I have several friends that have lifelong partners, but have no plans to get married. It isn't out of defiance just to "stick it to the man" or anything, they just don't want to. If it's legal, is it really up to us to judge whether it's right or wrong? Marriage is traditionally a religious institution, and those who don't care for marriage but still care to have children may be "sinners" in the eyes of religious people, but isn't it a great thing that those of us who aren't specifically religious don't have to have the approval of those who are?
I may have more to say on it, but I can't remember at the moment. I hope my opinion can provide some food for thought.
