Tell me about your oral instruction.

There is not a simple linear relationship between emotion and sexual behavior. Everyone's preference and comfort for sex are different, which depends on personal experience, beliefs, values and personality characteristics. Therefore, you can't judge whether a person loves you only by his sexual behavior.

Sex is a sensitive and private field. For some people, oral sex may not conform to their personal preferences, cultural concepts or comfort. This doesn't mean that she doesn't love you. It is more likely that she has different views on oral sex or has other reasons, such as personal preference, physical discomfort or other psychological factors.

I suggest you communicate with your girlfriend in an open, frank and respectful way. By listening to each other's thoughts and feelings, you can better understand her position and reasons. It is important to avoid confusing sex with love, but to build mutual trust and respect through communication and understanding.

The most important thing is to respect each other's wishes and comfort, and make sure that you are both sexually aware. If there are differences in sexual behavior, you can seek the help of professional sexual health counselors or psychological counselors to better solve this problem.

Remember, love is based on mutual understanding, respect and communication, and sex is only a part of love relationship.
