Is there any treatment for not achieving ejaculation?

Patient's question:

Detailed medical condition and consultation purpose: Over the past two weeks, I have had three instances of not achieving ejaculation with my girlfriend, but I can achieve ejaculation within less than 10 minutes with my hand.
Duration of the current illness and persistence: Two weeks
Other: I would like to ask the experts, what could be the reason for this? Are there any treatment methods available?

Doctor's answer:

Psychological and Sexual Education Therapy
Primarily used for patients with functional anejaculation. When treating this type of patient, both partners should be taught about the anatomy, physiology, and sexual response of the genital organs, while also paying attention to sexual positions and methods, eliminating erroneous beliefs, and harmonizing the marital relationship. The female partner should cooperate with the male to help alleviate his sexual anxiety, enabling him to engage in sexual activity in a state of full relaxation and arousal. This enhances stimulation intensity, allowing the penis to receive more sexual stimulation and ultimately achieving the goal of treatment.
Sexual Behavior Therapy
This primarily involves sensate focus training, which helps patients gradually adapt to and become familiar with the sexual process, improving their awareness of sexual responses, fully enjoying sexual pleasure, and reducing anxiety and fear related to intercourse. Additionally, to further enhance stimulation of the penis, pre-intercourse masturbation, adjusting the frequency and timing of intercourse, changing positions, and the female contracting her pelvic floor muscles after the male insertion can be employed to further induce ejaculation.
