The very last sports physical I had for wrestling, the doctor I had in my youth specifically checked to see if I had a tight foreskin, twice.
After she did the rectal exam, (only time I had one) I was hard, and she told me to turn around and lie down on my back on the exam table. I hid my genitals with my hand, but she told me to move my hands to my sides, and asked me if it hurt when my penis was "like this," and pulled the skin back.
She also retracted the skin earlier when I was not erect, so she did it twice.
I think she had me turn around after the rectal exam to check if I had an erection, and to see if my foreskin was able to move freely. I wonder if that is normal for doctors to check your penis in such state during a physical? She only did this the very last year I saw her before I transferred to an another doctor for adulthood.
