Not without a medical exam, I think.\n\nThey used to say that a woman bled after sex the first time, but that is not always the case and there are times for women who have had sex before to bleed after intercourse - so that method is not really concrete.

When women are anticipating sexual activities the vagina secretes a fluid that is used for lubrication during sex. So when he was touching you down there your body was gearing up for sex even if you weren't going to have sex. It is a natural thing to happen so you don't need to see a doctor about it.

This is what the American Cancer Society states:\nAn erection occurs when the brain sends a signal down the spinal cord and through the nerves that sweep down into the pelvis. Some of these important nerves run along both sides of the prostate gland. \n\nWhen this signal is received, the spongy tissue inside the shaft of the penis relaxes and the arteries (blood vessels) that carry blood into the penis expand. As the walls of these blood vessels stretch, blood races into the penis at up to 50 times its usual speed. The blood fills 2 spongy tubes of tissue inside the shaft of the penis. The veins in the penis, which normally drain blood out of the penis, squeeze shut so that more blood stays inside. This causes a great increase in blood pressure inside the penis, which produces a firm erection.

No- this is not normal at all and should be checked out by your doctor. Bleeding after sex can be due to many reasons including cervical dysplasia, chlamydia, gonorrhea, vaginitis or cervicitis, cervical polyps, trichomoniasis, yeast infection, endometriosis or adenomyosis, uterine polyps, and fibroids. Please do get checked out to determine what the exact cause may be.

No it is NOT normal to bleed during or after sex. You really need to go see a gynecologist ASAP. There are many things benign and serious that can go wrong with your body despite having a partial hysterectomy. You still have ovaries and a vagina that need to be checked. Ladies that have hysterectomies still need to get paps, its a smear of the vaginal cuff. See your doctor please.

Yes.  Sometimes the blood isn't very red at the beginning and the end.  Expect it to be weird before it gets regular- just keep supplies with you just in case and keep track of it.

It takes awhile for the blood to exit the penis and go soft again. Don't think you're wonderwoman it happens in every guy. Takes about 5 minutes sometimes longer if she cuddles with you and your tall tommy is rubbing her hips. I need to go jerk off

Temporarily. Most people experience a calm and relaxation after orgasm and you have a space where the issues that create hypertension are forgotten. If the sex becomes part of feeling good about your self and relaxing about ones relationship to life it can help to let go of the tension of false ideas that create high blood pressure.

If you haven't had intercourse before then your hymen may still be intact.  His finger is tearing a little at a time repeatedly causing the bright red bleeding.  Since last time it was brown blood, it was old and your hymen is probably totally torn now.\n\nYes, you can transfer semen that way.

Hi there, it's not abnormal to sometimes bleed after intercourse, I'm assuming you weren't a virgin, because sometimes the angle of penetration might bump your cervix or possibly the friction of movements can irritate or make a tear similiar to a papercut but without pain.  There might have been some residue left over from your period previously that was jarred too that came out. I wouldn't worry about it but if it happens frequently after sex or just bleed on it's own, make sure you see a doctor.  If you had an infection that was bleeding, you would have pain, possibly discharge along with the blood, itching, burning etc.  It's happened to me before a few times.  Don't worry unless it starts happening alot.

'The blood rush after climax depletes the muscles of energy-producing glycogen, leaving men feeling physically drained. \n\n'Because they have more muscle mass than women, men become tired after sex and this subsequently leads to them feeling sleepy.'

If you have these feelings after sex, it means you have emotional problems that need to be treated by a professional. Sex is a beautiful act that should be performed between people that love each other, and would never leave you "sick and empty." I hope you seek help because this reaction is not normal.
