Pain After Oral Sex
The head of the penis is a very sensitive part of the body. Each person is different, but friction caused by oral sex can lead to irritation, soreness, and swelling of the penis. In the future ask your girlfriend to ease up on the suction during oral sex. Remember to avoid STDs with oral, vagina or anal sexual activity you should always use a condom.
You never mentioned how long your penis was swollen just that you had no numbness, problems with getting an erection or urinating. If this symptom happens again TeenHealth suggests you make an appointment with your healthcare provider.
If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist, contact your local teen health center or Planned Parenthood to see if they have men’s health services in your area.
A Planned Parenthood health center is a good option if you have concerns about cost or confidentiality issues. You can also contact your insurance company for a list of in-network providers.
