Washer

This is an embarrassment, but I have to tell it to someone. I am a Male,79 in reasonable good health. I do have allergies, mostly the swelling kind...but under control...till now. I'm a widower, but not sexually inactive. A few months ago I noticed an insatiable itch around my scrotum area. My doctor gave me atopic medication to curb the itch. It did not work. I went to an aging Dermitologist, older than me even. He saw nothing unusual. Urine test came negative. No lumps of anykind. Now back in 1988, I had a turp surgery. All went well and no problem there as far as I know. One day I had to experiment self satisfaction, to see if I can have an orgasim. I did, so no problem there, but I did notice that in the process, my penis, and my scrotum was very itchy , and although I had an erection during the process, the penis took an odd shape, almost like a large hive. Now, i said that I have allergies. For a couple of recent years the allergy would affect my toes. It would get little red and I had to rub the itch away. For a while I thought I had athletes feet, but there were no cuts or scratchs that usually accompany athletes feet. Now, my toes seem to go back to normal without the intense itch and perhaps traveled to my scrotum area. That is how my allergy's seem to affect me. From one part of the body to another at different times. But it rarely ever effected me there...only once in the past 20 years. It seems to happen each time I engage sexually. After the climax, the penis goes back to normal size and even the itch subsides, until the next time. I'm too embarrassed to tell my regular doctor, and the urologist that I went to is a very nice doctor, but i have no confidence in him. I also went for 7 years treatment to an allergist. Has any male here regardless of age, witness this problem too? Would love to hear from you and tell me what you did for it. Thanks, for reading.
