Possible Lichen Sclerosis?

Hi,
First of all, I would like to thank you for this truly outstanding resource. I've spent the last couple days reading through many of the threads on here. I feel like I have a much better understanding of foreskin-related issues than ever before. As an uncircumcized U.S. citizen, I'm familiar with the "when in doubt, cut it off" attitude towards the foreskin held by many physicians in the States. I'm exceedingly glad I still have my mine.

I'm 30 years old. I've had recurrent balanitis for several years. It has never been a big problem but it has always come back consistently, at least every couple of months. I've been prescribed clotrimazole at least twice. It seemed effective initially but then the balanitis (little red itchy spots on the glans) would return. Unfortunately, I often ignored it and didn't bother going back to the clotrimazole.
The most recent time I was prescribed the medication was about two weeks ago. The doctor also gave me a blood test for diabetes, which came back negative.

Until recently, I've never had any problems with my foreskin. It has always retracted easily and been relatively "loose" around my glans. About three months ago or so, however, my foreskin became very tight and I was unable to fully retract it. This happened after a day of particularly vigorous sexual intercourse, although I'm not sure if there is a connection. I originally assumed it was the result of heavy friction during sex, though.

I waited a few days and then I was able to pull it back but it was still very tight around the tip. At this point, I noticed a white ring encircling the foreskin. The skin is noticeably tighter there. It is painless, though. Since its initial appearance several months ago, it has not changed at all (after being much tighter for the first couple days.)

I have been using clotrimazole twice daily for about two weeks and it has had no effect on the white ring (although it has cleared up the red dots I had on the glans.)

Based on my research, I suspect that this tight, white ring of skin may be Lichen Sclerosis. I don't currently have medical insurance, so I am debating whether or not to try to get another doctor's appointment...particularly because of what I've read on here regarding the difficulty of finding someone familiar with this problem in the States.

I have included three photos of the affected area below. Any suggestions or ideas would be very much appreciated. Thank you in advance.
