1990 s, the condom usage in the United States has been gradually decline, especially among the young men.
According to the centers for disease control and prevention (CDC) study, from 2002 to 2002, the first sexual experience in the use of condoms increased from 71% to nearly 71% of teenagers.
But from 2011 to 2011, that figure dropped to 78%.
It didn't seem to fall very much. But sexual health researcher at the university of indiana Debby Herbenick, Ph. D, says Dr This decline seems to be more obvious.
One theory is that: young people have misunderstanding on a condom. They only use condoms for birth control.
Part of the problem is that the market marketing. In the 1990 s and early 21st century, the condom is another name for the fight against HIV and disease, the recent public health campaign emphasizes prevention of pregnancy.
At the same time, the use of "long-acting reversible contraceptive method" (LARCs) also increased among women.
These contraceptives in the form of arms implants and intrauterine device, and both better than condoms to prevent pregnancy.
According to the centers for disease control and prevention, the condom is 82%, the effective time and when used correctly, pills and LARCs effect is close to 99%.
But when it comes to sexually transmitted disease, condoms are the only way to protect you and your partner.
If we have a way to test, 40% to 60% of male college students who will detect the HPV positive results.
The incidence of chlamydia is also high, but have no symptoms, so the men are not even aware that she was ill.
HPV can cause tintin in later life, head and neck cancer. Meanwhile, chlamydial infection may disrupt your internal pipeline, you make it difficult to have children.
Then there's another about don't use a condom the culprit: "many young men learn about sex through watching porn, and you almost never see wear condoms,"
This is common in porn movies - or we have heard that before his partner to relax, he will go out to masturbate.
The young who adopt this approach, mistakenly think that they don't have to worry about pregnancy, because they quit before reaching orgasm.
Of course, even if you quit, your partner will still be pregnant.
For you and your partner, the most safety measures is the female condom and LARCs together or tablets.
I don't think a man will always wear a condom, in a long-term relationship, if two people are loyal, healthy, then contraception is, in fact, the only effect of a condom.
However, if you and more sex, so you will need to use a condom.
Want to make sex more safe, passion?
In 2012 in the Journal of Sexual Medicine (Journal of a soon-to-be-published) published a study found that when men report that when they are happy about your condom feeling, Sexual pleasure will increase.
Before we also have special article tells us how to choose suitable size of condoms, you can go to look at, believe that will help you.
After, of course, if you wear a condom, apply some lubricant in the outside, will also increase your sexual experience, hurry to try it with your lover!
性研究人员指出了一些潜在的罪魁祸首，这其中也包括色情片。
最近，性研究人员发现了一个令人不安的趋势:自上世纪90年代以来，安全套在美国的使用率一直在逐步下降，尤其是在年轻男性当中。
根据疾病控制与预防中心(CDC)的研究，从2002年到2010年，在第一次性体验中使用套套的青少年比例从71%上升到近80%。
但从2011年到2013年，这一数字下降到78%。
这看起来并没有下降的很厉害。但是印第安纳大学的性健康研究员Debby Herbenick, Ph.D博士说，这种下降似乎更加明显了。
其中一个理论是:年轻人对套套产生误解。他们只是为了避孕才使用套套。
部分问题在于市场营销。在20世纪90年代和21世纪初，避孕套是抗击艾滋病毒和疾病的代名词，最近的公共卫生运动强调预防怀孕。
与此同时，使用“长效可逆避孕法”(LARCs)在女性中也有所增加。
这些避孕措施以手臂植入和子宫内避孕器的形式出现，而且两者都比避孕套更好的防止怀孕。
根据疾控中心的数据，避孕套的有效时间为82%，而在正确使用的情况下，药丸和LARCs的效果则接近99%。
但当涉及到性病时，避孕套是保护你和你的伴侣的唯一方法。
如果我们有一种方法来测试，40%到60%的大学男生会检测出HPV的阳性结果。
衣原体的发病率也很高，但都没有症状，所以男人们甚至没有意识到自己已经患病。
HPV可以在以后的生活中引发丁丁、头部和颈部癌症。与此同时，衣原体感染可能会扰乱你的内部管道，使你很难有孩子。
然后还有另一个关于不使用套套的罪魁祸首：“很多年轻的男人通过看色情片来了解性，而你几乎从来没有看到过安全套的磨损，”
这在色情电影中也很常见——或者我们听说过，在让他的伴侣放松之前，他会先出去手淫。
年轻人采用这种做法，错误地认为他们不必担心意外怀孕，因为他们在达到高潮之前就退出了。
当然，即使你退出了，你的伴侣还是会怀孕的。
对你和你的伴侣来说，最安全的措施是将避孕套与LARCs或药片结合在一起。
我不认为男人会永远戴套套，在长期的关系中，如果两个人都是忠诚健康的，那么避孕实际上是套套的唯一作用。
但是，如果你和多人发生性关系，那么你就需要使用套套了。
想让性行为更加安全、激情吗？
2012年在《性医学杂志》(Journal of Sexual Medicine)上发表的一项研究发现，当男性报告说，当他们对自己的套套感觉满意时，性快感就会增加。
我们之前也有专门的文章告诉我们如何挑选合适尺寸的套套，你可以去浏览一下，相信会对你有所帮助。
当然，如果你在戴上套套之后，在外面涂一点润滑剂的话，也会提高你们的性体验，赶紧跟你的爱人去尝试一下吧！
