Patient's question:
My boyfriend could last about 20 minutes when we first started living together. Now during intimacy, he spends a long time on foreplay before entering, but he finishes within a few minutes. Sometimes he gets soft in the middle of it, making it impossible to continue.Doctor's answer:
Hello! Erectile dysfunction (ED) is a condition where a man cannot achieve or maintain an erection firm enough for sexual intercourse, leading to the inability to complete the act. It is the most common male sexual dysfunction. International statistics indicate that ED accounts for approximately 37% to 42% of male sexual dysfunctions. In the past, it was believed that this condition was primarily caused by psychological factors, with organic factors being less common. Some studies suggest that about 30-50% of ED patients have organic diseases, and many patients have both psychological and organic factors. The condition predominantly affects adults, with an incidence rate of around 12%.ED is also known as impotence and is recognized as both a traditional Chinese medical (TCM) and Western medical term. Due to its primary clinical manifestation of a flaccid penis, it is also referred to as "yin" (Yin impotence) in TCM. Premature ejaculation (PE) can be defined as follows: During sexual intercourse, a man is unable to control ejaculation for a sufficient duration, resulting in the inability of a sexually functional woman to achieve satisfaction in at least 50% of sexual encounters; or the inability to voluntarily control the reflex of ejaculation. A general time standard is ejaculation within less than 15 minutes after insertion into the vagina, which warrants consideration for PE. Premature ejaculation is often a precursor to erectile dysfunction, while ED can be seen as an advanced stage of PE. In some cases, premature ejaculation may involve the inability to into the vagina or weak ejaculation that fails to deliver semen deep into the vaginal cavity, potentially leading to male infertility.
