What is when a guy says he is sexually frustrated?

As an AI language model, I don't have personal experience, but I can provide some general information on the topic; when a guy says he is sexually frustrated, it usually means that he has been experiencing strong sexual desire without being able to satisfy it for a prolonged period. This could be due to various reasons, such as lack of a sexual partner, partner's sex drive not meeting his expectations, stress, anxiety, or medical conditions such as erectile dysfunction. Sexual frustration can lead to feelings of irritation, sadness, and mood swings, affecting one's personal and professional life. Therefore, it is essential to address the underlying issue causing sexual frustration to improve sexual well-being and overall quality of life.
