Hmmm.
I think the more relevant question, here, is -- What part of you is asking the question?
If you are a Christian, then there is no question -- You believe that premarital sex is a sin. ...BUT. You ALSO believe that, if you sin and you repent, then you WILL be forgiven. So interpret that as you will, lol.
If you don't know what you believe with regards to religion, then well -- there's a good place to start.
If you are not particularly religious, or believe in a religion that simply doesn't have a stance on the issue, then there are probably 2 things you'd want to consider: your temperament and social expectations.
First of all, it is important to have some sort of moral standards regarding your behavior. There are a few different ways to look at this, depending on a person's values. For a person who values waiting, you could say that the fewer people you have slept with by the time you get married, the more important your spouse will feel to you. But on the other hand, you could also look at it this way -- You could tell your spouse, "I've slept with 23 guys, but I chose to marry YOU because I wanted to have sex EXCLUSIVELY with YOU." And that can really mean a lot to someone. It just depends how you look at it I guess.
In my mind -- now this is just a personal view, and totally disregarding religion -- premarital sex is essential to the survival of a potential marriage. The truth is, people have varying libidos. I heard a story of a guy moving in with a chick who wanted to have sex like, literally six times a day, and the poor lad was barely getting any work done. Now, there's ways you can work around that (vibrators, etc), but come on...Let's not be ridiculous.
Also, a person's sexual style is as individual as the person. Some people like S&M, or dirty talk, or dressing up...for others, that stuff is just plain WEIRD. You have to especially be careful if one partner is a virgin and the other is not. I mean, you don't want to marry like, a conservative Christian and end up getting scolded on your wedding night for using the Lord's name in vain...that would seriously kill the mood lol.
This is how it went for me. I cannot believe I am sharing this here, but it's a very unusual story and I did learn from it, which is why I'm sharing it. I was raised with really high standards in men -- I mean, my father, brothers, and uncles are all very handsome, VERY smart, and VERY good people. Therefore I have always been very picky about the men that I have warmed up to, and as a result, I found myself at age 22 and STILL had never french-kissed a guy. And I was getting into my 20's and you know...sex is ALL anyone talks about in their 20's, and it became an issue of great anxiety for me, from a social perspective. You see, at first, I was very open and honest about being a virgin -- I mean, I didn't care what people thought of me. It's not like it was because I was ugly or anything. But I started to realize that when I said it, I'd get one of two reactions: Either "Awww that's so sweet," or "WTF is wrong with you??!" Either way, I'd be treated differently from that point on, and I'd feel like, since I had never had sex before, then my opinions on the subject were not valid. That, coupled with my Catholic upbringing, caused a LOT of serious emotional and sexual frustration that built up in me and what finally happened was, in the midst of some boy drama, I went out one night and got VERY drunk and had a one night stand. And, though emotionally I have no real regrets (I know this sounds awful, but frankly I was pretty relieved to just "get it over with"), it was still pretty pointless, and morally wrong (In my opinion) and could have been avoided had I dealt with my sexual frustrations in a healthier way.
A lot happened in the months after that...And ultimately I decided, okay I've done the casual sex thing...and my feeling about that now is, been there, done that, I'm ready to move on to bigger and better things. I have a lot of patience and fortitude built into my temperament...Meaning, I have the WILL to hold myself to pretty high standards...And therefore, I concluded that I should make the effort to do so. So I am waiting for not just love, but IN love.
I also come from a very Catholic family who makes a big fuss over sex and significant others (every time I bring a guy home, they absolutely SMOTHER the poor lad) so having (i.e. SNEAKING) a meaningless sexual relationship, coupled with the possibility (however small) of getting pregnant and shaming the family or whatever, is just not worth the trouble and fuss to me. I've got to focus on school right now.
And also, another issue that was barely touched on in here:
Oral sex is sex to me. Simple, really. I see it as a sort of cheap way out, when in fact you've pretty much seen everything there is to see. So I guess I don't believe in "technical" virginity.
You know, oral sex has always felt like very much a cop-out to me, too. It is a VERY popular thing (around here, at least) for young people to have oral sex while still, in their minds, "saving themselves" for love or marriage or whatever. But, I mean, I've seen people sleep around with a lot of people, and even if it's just oral sex, I still consider them sluts. It still involves taking off clothes and whatnot, and a large degree of vulnerability, etc, and for me -- perhaps this is wrong, but -- intercourse is not that big of a step beyond it.
But for what it's worth, I do feel more "connected" to a person during intercourse. It's very much a bonding experience for me...well, if I love the person, anyway. I have had casual sex, too, so it's perfectly possible for a person not to make much of a distinction.
...But I dunno. That is definitely a very personal thing, and really, I still don't know how I feel about it.
I will say this -- I was a relatively late bloomer and I do feel like I missed out a bit, especially since SO much happened to me at once. In fact one of the reasons I was relieved to "get it over with" was because I was worried that I would fall too far behind my peers in my social/emotional development. But fortunately, I was plenty old enough and found that the learning curve was not as steep as I anticipated. (read: Apparently, I'm a natural! hehe)
Also, I learned this: Sex, when it's with the right person, is the FUNNEST THING EVER. Drunk, casual sex -- boring as crap, and it's never any good either. And it's not worth doing anyway cuz you don't remember it ha ha. Having been there and done that, my feeling towards it is, it has to be with someone you're TOTALLY comfortable with, and would tell them ANYthing. And also, don't take it too seriously...Laughing makes sex SO much more fun and eases the tension and makes it better for both people involved.
At the VERY least, my opinion is that you should not have sex with any guy who you think would be a bad father. Because accidents DO happen, and I have a laundry list of friends who were screwed up because they had sucky fathers, and I would never forgive myself for being responsible for that. It's a pretty good rule to have, I think. I mean, it makes sense lol.
...that's just my $.02.
