This patient support community is for discussions relating to relationships, abstinence, arousal problems, birth control, cohabitation, commitment, communication, couples counseling, desire, sexual technique, and sexually transmitted diseases (STDs).
Complications such as mentioned above may arise, but as you said those are primarily from careless activities. Keep in mind that this particular forum is patient-to-patient. You might want to think about talking to Sue Johanson of the Sunday Night Sex Show (not sure if it's called that) to get a real expert opinion. Or pay the fee to post on the doctor-to-patient forums. You can learn a lot just browsing this website and reading previous posts. Either way, good luck!
