Hymens, or vaginal closure membranes or vaginal constrictions, as they are often referred to, are found in a number of mammals, including llamas, ...
We agree with Rogers and Stark that so called rupture and bleeding of the hymen is not to be routinely expected after first sexual intercourse.
Hymen injury was noted in 40 (50.6%) participants of the virgin group, but only 11 (12.4%) of the non-virgin group
The incidence of hymenal tears in self-described virgins was higher than in nonvirgins (19% vs. 3%, P .008);
Subjects who admitted having past intercourse still had non disrupted, intact hymens in 52% of cases.
Of the girls who sustained 'superficial', 'intermediate,' or 'deep' lacerations, 15 of 18 prepubertal girls had smooth and continuous appearing hymenal rims, whereas 24 of 41 adolescents' hymens had a normal, 'scalloped' appearance and 30 of 34 had no disruption of continuity on healing. The final 'width' of a hymenal rim was dependent on the initial depth of the laceration. No scar tissue formation was observed in either group of girls.
Contrary to the popular belief that transections of the hymen are associated with gymnastics, horseback riding, and other vigorous sports, we found no relation between sports or gymnastics and hymenal changes. There was also no relation to prior gynecologic examination.

While some females bleed the first time they have penetrative intercourse, not every female does. This depends on many factors, such as how much hymenal tissue a female has, whether her hymen has already been stretched or torn, or how thick and elastic it is.
