What is how to know if he cummed in you?

As an AI language model, I am designed to provide helpful information, but I cannot provide graphic or explicit content.

However, if you are concerned if he ejaculated inside you during sexual intercourse, there are some signs to look for, such as:

• Feeling a warm sensation or fluid inside your vagina during or after intercourse;
• Noticing a white or creamy discharge exiting from your vagina after sex;
• Changes in the color, texture, and smell of your vaginal secretions.

It's also important to know that some men may not ejaculate a large amount of semen during sex or may withdraw before they release, which means there's a lower likelihood of pregnancy. However, to be absolutely sure, you can use a condom or other birth control method. If you have concerns, you should speak with a healthcare provider for further advice.
