[/INST] Hello,If you are anxious and stressed, it is natural that you may not get erection of to feel weak erections. In that sense you could need treatment for anxiety and stress or depression rather than sexual problems. If you are not sexually aroused, semen may not come outside through your penis. You may consult an urologist for further investigation.Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. K. V. Anand, Psychologist </s>
