No, unless you break your hymen
Here is an article on the hymen: http://en.wikipedia.org/wiki/Hymen
Yes, of course
All penetration will rupture the hymen. Usually something the size of an erected penis will rupture the hymen if there is one there it can be ruptured by riding a bike.
Hymen
There is no proper condition for a hymen. Either you have one or you don't. You might be born without one. And you wont know until you loose it. Don't put emphasis on the hymen. It has no role in life or you body. It's just a remnant after you were in the womb and the vaginal canal was supposed to be closed.
If a girls hymen has not already broken, it normally breaks the first time that she has sex. The hymen is a thin piece of skin at the entrance to the vagina. When it breaks, it can be a bit painful (kind of like burning and a bit like stinging) and there is sometimes some bleeding. Some girls don't experience any pain or bleeding when their hymen breaks though. However, the hymen is often broken during normal day-to-day activites such as cycling, horse riding, running, jumping, dancing, doing the splits etc. Some girls aren't born with a hymen.
Yes it is possible to tear the hymen through horseback riding
No, not all girls are born with a hymen. The hymen is tissue left over from development within the womb - at one point there was no vaginal opening, as the vaginal opening developed the skin that was covering that area retracted and became the hymen, but not all girls were born with a hymen. The hymen can be worn away, stretched, or torn partly or fully but usually even if torn fully or worn away it doesn't disapear completely - it's still there, just no longer in tact. Although sometimes a doctor may cut away a woman's hymen for medical reasons. There are also then girls who were born biologically male, thus wouldn't have a hymen.
Girls don't have cherries and nothing gets popped. A girls hymen can be torn from vaginal penetration at any time, this has absolutely no relation to the menstrual cycle and has no effect on the menstrual cycle - thus her period will start when it is due, and if that happened to be after her hymen was torn then that's when it will start.
You cannot lose your virginity from horseriding. This question probably stems from the myth that a girls hymen (skin covering the vaginal entrance) can break from horseback riding. This is not a myth, but fact, but simply breaking your hymen does not mean that you have lost your virginity. Nowadays, many girls break their hymen before having any sexual contact. It is neither a good nor bad thing, just a fact of the world. Please do not stop doing something that you love, like horseriding, for fear of losing your virginity or breaking your hymen.
You can rip your hymen by having sex ,doing the splits,fingering,hard working out(sports) and other ways to
Many girls and tear or dilate their hymen as a result of partaking in like bicycling, horseback riding, gymnastics, inserting tampons or while masturbating. Other case is that they tear only partially.
A hymen is a fold of skin/mucous membrane in a girls vagina. A broken hymen was usually a sign of intercourse and a way of checking if a girl is a virgin. Nowadays however, it's generally acknowledged that a broken hymen alone is not proof of intercourse as it can break doing gymnastics, horse or bicycle riding, or for several other reasons. The size and texture of the hymen can vary greatly, and can in some cases be completely absent from birth. The word Hymen itself is derived from a god in the ancient greek mythology, Hymenaios (alternative spellings: Hymen or Hymenaeus). He was the god of the wedding hymn (the song sung to or by the bride and groom at the wedding).
The hymen is a remnant from when the vaginal entrance was closed when you were in the womb. Some are born with one and others without. Some hymen are thick, others thin, can cover big parts of the entrance or little. It can break doing sports and others will need help from a doctor because it's so thick it hurts too much for intercourse. As soon as you are born it has no purpose.
No one knows that. The hymen can break very easily for some when doing sports etc and they might never have sex. It's impossible to keep track.
Nope not at all. The hymen is only a remain from the time in the womb and has no effect on the body, broken or otherwise.
Not at all. Most of the time it's not a choice you make. Some are born without ones and often it breaks by itself. The hymen is a remnant from when you were in the womb and the vaginal canal was supposed to be closed. It faded as you were closer to birth and as you were born it has no purpose.
