Is this a sexual dysfunction?

Patient's question:

When I was young, excessive sexual activity might be related to some of the symptoms you have now. Currently, when having sex with my girlfriend, I get hard but then get soft very quickly. Also, many times, I finish in less than a minute. Is this a sexual dysfunction?

Doctor's answer:
