Erection Problems

Patient: Hi there,I have 2 questions that I would like answering please. They are both highly personal and embarrassing. The first is that over the past 6-8 Months, I have been waking up in the middle of the night with an erection that stays for a couple of hours. This keeps me awake and I find it difficult to get back to sleep. Subsequently I am tired throughout the day. My second problem is that over the last 12 months I have suffered with premature ejaculation. This has never been an issue before, but since the birth of our second child, it has not gone away. Although my wife says it is not an issue, I would like to sort it out once and for all as it is starting to get me depressed. What can I do? Does hypnotherapy work? Please help!
