I came across Fire's question and remembered something.
I know we're not supposed to share details, but one time, my boyfriend was fingering me.. and he was going pretty hard, it actually hurt. When he finished, there was blood, all over his hands, the bed, everywhere. At first I thought that he might have cut me.. but he said he probably broke the hymen? - if that's the correct word.
First of all, most women who have hymens in the first place (since some are born without them) find that they have been eroded before first sexual activity anyway (through childhood accidents, falling down, gymnastics, horseback riding, tampon use, masturbation, etc.).
Based upon your description, I'd guess that he probably cut you or abraded the delicate tissue, thus causing the bleeding. A hymen is just a thin layer of tissue partially covering the vaginal opening. A portion of the bleeding might have resulted from some stretching or tearing of that (if indeed you had one at the time), but I'd really guess otherwise from what you've said. Along with that, if someone is preforming manual sex on you to the point where you are experiencing pain, then you need to speak up because pain can often indicate that some sort of damage is being done. Some latex gloves and lubricant would solve this problem nicely, along with a somewhat more gentle touch from your partner. That tissue is very delicate and very easy to injure.
(As Miz Scarlet said in the other post though, really huge amounts of blood are unlikely unless you had started your period at the time.)
Along with that, pain during earily sexual intercourse is often not caused by the presence of a hymen (especially since one is not always present). Often women experience pain due to anxiety or fear of pain that causes them to tense up or from a simple lack of arousal for whatever reason.
Rather than starting a whole new topic for something that is a response to someone else's topic, next time reply in the original topic instead. It just helps us keep things neater and is easier for the search engine to locate. Thanks!
