There is a good possibility that you are describing a "skin bridge". This ocurrs in circumcised males when the cut foreskin attaches to the head (glans) of the penis and heals. Another possibiliy is that he has some scar tissue from a circumcision operation (or possibly another operation or injury).
The good news is that if this is indeed a skin bridge, it can be easily corrected. There is a very good chance that scar tissue could also be easily corrected.
Of course, if your husband is not circumcised or has never had an operation/injury, then neither of these two conditions would be the cause. However, I suspect that there is a good chance that it is. Additionally, it is possible that this is simply the way he was born - especially if he is not cause any pain or discomfort and it has not changed over time.
In any event, I know that your husband is embarassed to see a doctor, but please try to assure him that there is nothing for him to be embarassed about. He has a legitimate health concern and there is a very good possibility that this can be corrected easily (maybe even in the doctor's office). Health professionals see patients with this type of concern day-in and day-out.
If you are interested in reviewing some pictures of skin bridges, please send me an IM. The pictures are graphic and, as such, I do not want to include the link here.
Thank you and please let me know if you have any other questions.
