Why Do My Legs Feel Weak After Ejaculation?

Ejaculation, also known as cumming, jizzing or shooting your load, happens when the vas deferens (tubes that store and move sperm) release semen. This sticky white liquid contains sperm and whitish, protein-rich fluids that nourish them.

Sexual arousal can cause temporary changes in blood flow that may lead to leg pain in some individuals with pre-existing vascular concerns, such as varicose veins. A health care professional can help manage this symptom.


Just like any intense physical activity, sex causes your body to work hard. Your back and leg muscles, in particular, are getting a workout. This makes you tired, but it doesn’t make your muscles weaker in the long run.

Alternatively, your legs may feel weak after sexual activity due to an underlying health issue. For example, if you’re pregnant, hormonal changes may cause leg fatigue and tingling after sexual activity. This can be a sign of a condition called postorgasmic illness syndrome, which has been linked to anxiety and depression.

Other potential causes of leg pain after sex include muscle strain, cramps, and nerve compression. Muscle strain and fatigue may be caused by overworking the muscles during sexual activity. Stretching and reducing the intensity of sexual activity can help prevent this. Cramps are involuntary muscle spasms that can be painful and are usually caused by dehydration or electrolyte imbalances. Keeping hydrated and eating a healthy diet can help prevent them. Nerve compression may be a result of specific sexual positions or movements that put pressure on the nerves. This is more common in women and is often accompanied by numbness or tingling.

Rarely, vigorous sexual activity may lead to a blood clot in the deep veins of the legs (DVT). Although this is uncommon, it’s important to seek medical attention if you experience severe or persistent leg pain after sexual activity.


If a man doesn’t want to take drugs for PE, there are behavioral techniques that he and his partner can use. One such program is called the “stop-start technique,” wherein the patient and his partner stimulate the penis until he feels the urge to ejaculate, then they stop stimulation until the urge passes. A similar approach is the “squeeze technique” wherein a man and his partner squeeze the glans of the penis at the moment when he begins to feel the urge to ejaculate.

Psychotherapy is another possible treatment option, though this focuses on the underlying mental health problems that might be causing the problem. Counseling with a sexual therapist could help a man work through relationship issues that might be contributing to the problem, and it may also be helpful in finding ways to reduce his performance anxiety during sex.

It is important to note that, despite what many people believe, a person does not need a penis in order to ejaculate. In fact, it is the urethra that does the actual squirting, which can consist of both semen and urine.

Some men have difficulty reaching orgasm, and these problems might be caused by psychological factors such as a traumatic childhood or a restrictive upbringing, or by certain medications or by conditions such as thyroid disorders or prostate infection. In addition, some men might experience a condition known as retrograde ejaculation, wherein the semen travels back into the bladder instead of out of the penis (Althof, 2016).

The good news is that there are many things you can do to prevent weak legs after sexual activity. One is to make sure you drink plenty of water before and during sexual stimulation to avoid dehydration, which can cause leg cramps. In addition, practicing stretching exercises to prepare your muscles for exertion and working with your partner to find sexual positions that are comfortable for both of you can minimize strain on your legs.

Shaking in the legs after orgasm is a perfectly normal phenomenon called myotonia and occurs in most muscles of the body, not just those in the genital area. This is because when you reach orgasm, the muscles in your genital area and the rest of your body are contracted or tightened up and when they relax at the end of orgasm your legs shake.

Premature ejaculation is when you ejaculate sooner than you or your partner would like, which happens to about a third of men (Crowdis, 2022). Several theories have been proposed to explain the causes of PE including anxiety about sexual performance, masturbation patterns, relationship stress, medications that can reduce arousal or delay climax, penile hypersensitivity and conditions such as thyroid disorders or prostate problems.

Delayed ejaculation is when it takes a long time to ejaculate, which can also be caused by anxiety or medication. In addition to treatment for the underlying condition, using lubrication and engaging in sexual activities that reduce stimulation can help with this problem.

Other Symptoms

Ejaculation is controlled by signals from the brain. When a man is sexually stimulated, these signals cause the muscles of the penis to tighten and semen to be pushed out. If a man has a condition that causes him to ejaculate prematurely or not at all, he can experience leg weakness after sex. This can be a very distressing problem for both him and his partner. There are a number of different treatments that can help to alleviate PE.

Medications can be prescribed to relieve symptoms that may be contributing to the condition, such as muscle relaxants to reduce muscle tension, nerve pain medications to control any discomfort from nerve damage, and anti-inflammatory medication to improve circulation. Other treatments may include hormone therapy, if the underlying problem is caused by hormonal imbalances.

Pregnant women who are experiencing leg pain after sex should be seen by a healthcare professional, as this could be a sign of a serious medical issue, such as deep vein thrombosis (DVT), which is a blood clot in a vein, typically in the legs. Vigorous sexual activity can dislodge a clot or contribute to the formation of one, and if left untreated, can lead to a life-threatening condition called pulmonary embolism. The healthcare professional will be able to recommend treatment options that can minimize the risk of DVT.
