Sperm entering the body is an important step in getting pregnant. However mere deposition of semen does not always result in pregnancy.
Some women may also experience spotting and cramping after sexual intercourse. This is usually a sign that sperm has entered the vagina and fertilized an egg. This is called implantation.
Ejaculation
Ejaculation is the release of sperm from the male body during sexual activity. This is typically done through the penis and occurs during orgasm and sexual climax. The penis hangs limp in most men but becomes stiff and erect during sexual stimulation (orgasm). Muscles throughout the body contract, including those around the reproductive organs, to cause the penis to open and the sperm to flow out. The sperm is mixed with seminal fluid from the testicles and prostate gland to form semen. The sperm moves through the vas deferentia, tubes that run down the base of the penis, to the beginning of the urethra.
Semen contains millions of sperms. Once it exits the penis, it flows into the woman’s vagina. The sperm can then enter her egg in the fallopian tube, fertilize it, and grow inside her uterus. A healthy sperm can live up to 5 days in the vagina.
Women can also feel sperm entering their bodies during oral sex. A woman can choose to spit or swallow the sperm, which allows them to experience some sexual pleasure. If the man has a large amount of semen, it is common for him to pulsate and twitch during oral sex. While this sensation can be desirable for both partners, it is important to remember that sperm can still escape and lead to unwanted pregnancies.
Oral Sex
Oral sex, also known as cunnilingus and fellatio, involves stimulating a partner’s genital area with the mouth and throat. It is common among teens and adults. However, it is an effective mode of transmission for STIs such as herpes, syphilis, and gonorrhea, and can be an early cause of HIV infection. It is also a risk factor for pregnancy.
When a man or woman climaxes during oral sex, they may orgasm and swallow semen (or cum). This can lead to sperm entering their body through the mouth. However, most sperm do not survive the trip from the mouth to the stomach and cannot fertilize an egg. Additionally, women do not get pregnant from oral sex, because sperm can only enter the uterus through ejaculation.
Even though oral sex can feel intense, it is still important to use barrier methods and be respectful of your partner’s comfort levels. Try using lubrication or a water bottle to increase the friction and sensations, and explore a variety of techniques and pressures on your partner’s erogenous zones. Remember that everyone is different, so it can take a while to learn what feels good for your partner and what doesn’t. Using clear communication and sexual education can help you both enjoy a safe oral sex experience.
Vaginal Sex
During vaginal sex, the penis goes inside a woman’s vagina. Some people like it, some don’t. It can feel good when used in the right way, and it can lead to climax orgasm for those who aren’t able to reach climax through oral or anal sex. It can also be a powerful bonding experience between partners who are comfortable with it.
However, it is also a common cause of STDs. It’s important to use lube when vaginal sex and not put anything else (such as fingers or a sex toy) into the vagina that hasn’t been washed. This will help prevent infection and decrease the risk of STIs.
Women can sometimes feel sperm enter their vagina during this type of sex. This is because the erect penis and cervix are close together, and it can feel similar to anal sex.
Cramps aren’t uncommon during or after vaginal sex, and they can be caused by deep penetration or rough sex that causes abrasions on the vaginal lining. This is often accompanied by a slight amount of blood or irritation. It can also be a sign of tight pelvic floor muscles, known as hypertonic pelvic floor muscle syndrome, which can make penetrative sex painful.
While a woman may wash out sperm by urinating after sexual intercourse, it is impossible to completely flush sperm from her body. Even if she washes out all the sperm that entered her body, she can still get pregnant if a sperm reaches an egg and is fertilized.
Stomach
Sperm is a type of cell produced in the male reproductive system. It contains genetic information and helps with sexual reproduction. During sexual intercourse, sperm travels through the ejaculum to reach the vagina. Once inside the body, it fertilizes an egg to produce a baby. If a woman is fertilized by sperm, she may experience pregnancy symptoms, such as fatigue, nausea, and breast tenderness.
Sperm enters a woman’s body through the cervix during oral sex, and can also travel to her stomach if she swallows it. It’s unlikely that she will get pregnant from ingesting semen. The stomach is part of the digestive system, and sperm won’t survive in it.
Sperm can also cause itching in some women, especially if they are allergic to it. This is a rare condition called seminal plasma hypersensitivity, and it occurs when the body reacts to proteins in semen. Symptoms of this allergy include redness, swelling, and itching at the site where the semen has touched the skin. It is important to see a doctor immediately for this type of reaction. Women who are wishing to conceive should try to have sex during their fertile window, which is typically in the middle of their menstrual cycle. It is also important to use a condom to prevent pregnancy. In addition, lubricating the genital area can help with sperm penetration.
