Believe it or not, some teens do in fact want to remain virgins until marriage. If you are part of this group and have managed to survive high school with your virginity still intact, then you have completed a huge accomplishment. But you will learn early on that during college you will be faced with a variety of different challenges that might make your vow of celibacy hard to keep. But there are some easy and practical ways that you can remain a virgin in college.
The first thing you need to do is know your limits. If you wish to remain a virgin, this doesn't mean that you have to cast off the opposite sex indefinitely, but you do need to be open about your desire to remain a virgin and set your limits. As cliché as it may sound, many lose their virginities because they were "caught up in the heat of the moment." So it's best not to put yourself into a situation that could jeopardize your virginity. For example, if you have no intentions of surpassing passionate kissing (or whatever your limit may be) let your partner know and make sure that it never truly gets past that point. Know your limits and stick to them. If your boyfriend/girlfriend or date becomes agitated with your limits, then it's probably best you send them on their way and find someone else who is understanding. And there are people out there who are understanding, don't doubt that.
Another way to remain a virgin in college is to avoid temptations like alcohol. All too often males and females lose their virginities with a one night stand because they were drunk. Not only do they lose something in an instant they've worked their whole lives to keep, but drunken sex is also a common way people contract STDs and get pregnant (they tend to forget about using contraceptives). Avoiding temptations doesn't necessarily mean you can't have fun and go to parties, but you can either not consume alcoholic drinks all together, or at least make sure you drink responsibility. Limit yourself to one or two, nursing them rather than "chugging," and eat a good meal beforehand.
Lastly, don't make having sex, or rather not having sex, a goal. This is because if you constantly have it on your brain, it will become an active part of your thinking process. Once it's a part of your thinking process, you will either have to constantly resist the urge or you will let it take over your life—potentially sabotaging a wonderful relationship for fear that you will be pressured into having sex. Instead of worrying about having sex or not having sex, immerse yourself in your other interests and your school work. When your mind is stimulated and satisfied in other ways, you will become less interested in sex.
