挺好的科普,记得以前在国内读大学时候还有推销员到宿舍推销过
当时每人给发了一小包试用装,结果拆开大家都不知道什么玩意。终于有个懂行的出来“科普”了一下,结果全部被丢了。。。
不过至今没有使用过,有谁体验过的可以分享一下啊。前公司的澳洲女同事一直用这种来着,不过没有详问过。


将双手洗净,并拆除卫生棉条的包装,将包装内部的棉条完全展开
使用图示,大拇指和中指捏住外管底部,食指放在内管尾端
放置棉条的一般姿势,左边那种比较方便,站立且双腿微曲。还有一种一脚站在地上一脚踩在马桶盖上的“豪迈式”
将棉条对准阴道口
放轻松!并将棉条轻轻推入阴道,但推入时并非垂直推入,大约是一个斜上45°的角度
如果在推入过程中感到疼痛则可以自己尝试寻找一个适合的角度
当大拇指和中指触到身体时,食指便可开始推动内管
将塑料导管取出,棉条留在身体内,棉条的细绳应留在体外
左侧是正确的图示,棉条最好放置地深一些,若正确放置应该是不会有异物感的
使用完毕。捏住棉条留在体外的细绳,将棉条轻轻拉出另外表示楼主作为一个搞Research的人,转帖也太不学术了,看我给你个学术贴。

Hymenal findings in adolescent women: impact of tampon use and consensual sexual activity.
Abstract
We undertook a prospective study of 300 postmenarcheal female subjects (median age, 18.0 years) to examine (1) the relation of tampon use, sports participation, prior gynecologic examination, and consensual sexual activity to hymenal anatomy, (2) the factors leading to choice of tampons by girls not sexually active, and (3) factors related to ease of gynecologic examination. The sample included 100 subjects in group 1, who denied sexual intercourse and used only pads for menses; 100 subjects in group 2, who denied sexual intercourse and had used tampons; and 100 subjects in group 3, who gave a history of sexual intercourse. Sexually active subjects (81%) were significantly more likely than tampon users and pad users to have "complete clefts" in the lower hymen between the 2 o'clock and 10 o'clock positions (p < 0.001); tampon users were not significantly different from pad users (11% vs 5%). In subjects who were not sexually active, the presence of these complete clefts was not related to participation in sports or to prior pelvic examination. Although median hymenal opening diameter differed in the three groups (1.2 cm for group 1 vs 1.5 cm for group 2 vs 2.5 cm for group 3; p < 0.0001), the ranges of measurements were wide. Tampon users were significantly more likely than pad users to have mothers and friends, but not sisters, who had a favorable attitude toward tampon use. The best predictors of tampon use in a multivariate model were a favorable maternal attitude (odds ratio (OR), 5.3; 95% confidence interval (CI), 2.4, 12.1) and friends' use of tampons (OR 7.9; 95% CI 3.5, 18.1). Only 26% of speculum examinations in pad users were rated as easy compared with 56% of examinations in tampon users and 81% in sexually active young women (p < 0.001). The best predictors of ease of speculum examination were sexual activity (OR 15.9; 95% CI 1.9, 135.3) and tampon use (OR 3.6; 95% CI 1.0, 12.7). This large sample should provide useful data for physicians who testify in sexual assault cases and gives new information on the predictors of tampon use and ease of gynecologic examination in young women.
我就不逐字逐句翻译了,总结一下:
300个对象
1)100 用卫生巾,处女
2)100 用棉条,处女
3)100 性交过的
结果:
3组81%,2组11%,1组5%的对象10点和2点之间的处女膜完全破裂
这些1组和2组对象完全破裂不是妇科检查或体育运动造成的
平均处女膜孔尺寸 (p<0.0001。说明三组之间的区别绝基本绝对没有机率是偶然的):
1组: 1.2cm
2组: 1.5cm
3组: 2.5cm
