21 year old, experiencing bed-wetting for the last 5 years, frequency 2-3 times a month.some episodes follow a sexual dream in the form of masturbation?

Sleep disorder: Having bed wetting (enuresis) as an adult is an indication that there is very likely an underlying sleep disorder present such as sleep apnea. I would suggest you see a board certified sleep specialist and undergo a sleep study in a sleep laboratory.

Secondary enuresis: If u were dry before age 16-years. Need 2B checked with urinalysis & probably kidney & bladder ultrasound to rule out obvious pathology. If negative, discuss possible desmopressin (ddayp) with your dr. This reduces niocturnal urine production. Could take up to 0.6mg (3 x o, 2 mg tabs) nightly. Not related to masturbation, however could try to self indoctrinate to waken if such dream occurs..
