Pain After Ejaculation

Patient: Hello. I am sixteen years old and I have been experience extreme pain after ejaculation that seems to ease with urination. At first, I thought it was retrograde ejaculation due to holding the penis closed a few times to prevent ejactulation “mess”. But, after research, I do not feel that is what it is. As i said, the pain seems to ease with urination. Thanks in advance for the help!
