I was at the doctor doing the physical exam and when she (doctor is female) told me to pull down my underwear for the genital exam i got a huge erection and when she touched it fluid started to come out. She didn't say anything but I was really embarrassed. The worst thing was she had an assistant in the room with her (also female) who saw the whole thing I just don't know if this is normal or not, and I feel kind of ashamed for this happening. I am 12 btw.
