Hello.
Sleep orgasms--or wet dreams--are common throughout our lives. Some people only have them during adolescence, while others have them in adulthood, and vice versa. So stop worrying. There's nothing amiss here.
Your body is responding to hormonal surges during your sleep cycle, as well as emotional and/or psychological triggers. Relax and enjoy your sexuality for what it is: unique to you. Dr. J
