No norcturnal ejaculation

Patient: Hi doctor, my name is Abdeljalil i am 19 years old and i think i have a problem , i don’t have nocturnal ejaculation (i only had them twice few years ago) so it worries me , that’s why i tried not masturbating for 1 month to see if i’ll get them , i tried last month but nothing , so i tried stoping again for one month , now it’s exactly 1 month and stil no wet dreams .. my friends say i should go to see a doctor but since it’s expensive i would like first to know if this is a problem that i should be worried about or not , sorry for the awkward question , i hope you’ll take the time to answer me 🙂
