Sperm details are normal to diverge. Factors such as the time elapsed since your last ejaculation can determine the rate of sperm loss. If it continues fluctuating a lot or you have other symptoms like pain, burning, or blood, it's best to get checked. Otherwise, if it happens now and then, it is usually not a cause for concern. 

If you've had unprotected sex once and are worried that you might be pregnant, here are a few things to consider. The basic idea is that if sperm gets to an egg during intercourse then there could be a pregnancy. You may also experience symptoms such as missing your monthly period or feeling nauseated in the mornings. For clarity on whether this is true or not, use a pregnancy test kit. 

In case a person with male genitals has sex without ejaculating, pregnancy can still occur. There is also a possibility of conception if they pull out before ejaculation. Therefore, it is essential to use contraception every time. If you are worried about becoming pregnant, you may want to think about using birth control such as condoms. 

Many guys expe­rience ere­ction problems with condoms at times. It's normal. Plus, stress ofte­n impacts erections too. Don't consider it an issue­ of attraction. Stay open and reassuring with your partner. Try diffe­rent condoms. Importantly, communicate togethe­r to resolve things. 

Taking the blue­ pill may result in bleeding; be­ open with parents about this deve­lopment. One reason could be­ a side effect, prompting discontinuation and consulting anothe­r doctor. Notify adults if abnormal bleeding occurs; doing so promotes good he­alth.

When ejaculation appears before the due time, it's mostly known as premature ejaculation. This means that ejaculation takes place earlier than you or your partner would like, in the course of sexual intercourse. It is common and is often the result of stress, anxiety, or relationship issues. Make an effort to practice techniques like the start-stop method or deep breathing during sex. In some cases, therapy might be helpful. 

You may have a condition known as sexual asthenia. This can lead to weakness, body aches, and vomiting before or during sex. It may be caused by physical or mental issues such as stress. Make sure to rest, eat well, and talk to someone you trust about how you are feeling. If they do not go away after taking these steps then seek help from a medical professional who will give further advice on what needs to be done.

These signs might be because of many things such as stress or bad eating habits. But don’t worry, your brother’s test result was negative which is good news but to ease your mind, you should also take an HIV test among others after discussing with a doctor about the issues at hand.
