I'm 16 and 6 months, and I'm starting to feel as if I'm broken. I can't intentionally get an erection - only random ones. I can't masturbate. I can't orgasm. I can't ejaculate. All my friends can and it makes me worried. I've also never had a wet dream. I've also never been turned on or horny. It's really concerning now. Am I broken? Should I see a doctor?
