I had my first “adult” physical when I was 18 and a freshman in college. The doctor had me strip naked, which my pediatrician never did, and he asked me a lot about my sex life like when I started masturbating, how often I masturbated, when I first had sex and what I had done since getting to college. My pediatrician had talked to me about sex, but never in so much detail. I figured it was because I was an adult and in college and college kids have more sex.
He had me lay on the exam table and checked me out. It all seemed like normal stuff. Then he got a rubber glove and some lube and said he was going to examine my prostate. He had me roll on my side facing away from him and positioned my legs. He rubbed around my asshole for a few seconds and then pushed his finger in. His other hand was pushing on the area behind my balls. He told me I would probably get an erection and that it was normal. Sure enough, I quickly got hard. He kept fingering me and was rubbing the area behind my balls.
He kept talking and I felt like my dick was getting harder. Then he tells me he can feel a lot of fluid buildup and that I was going to have an orgasm. He said it was normal and not to be embarassed, just to relax and let it happen. I could feel I was getting closer, but I was embarassed. Then he said “we’re almost done” and pulled his finger out, but then pushed two fingers in. And he kept rubbing behind my balls and sometimes pushing up against them.
It felt like a normal orgasm when it started, but just as I thought it had peaked and was ending a second wave started that was extremely intense. He actually started rubbing my balls and just said something like “that’s it, just let it go” I ejaculated a lot and was embarassed at the noise I made and the way my body moved. I was shaking when it finished and he wiped my as and had be roll back on my back. My dick was still swollen and I had jizz all over me. He gave me some paper towels to clean up with and acted like everything was normal.
I was so embarassed about it and didn’t want it to happen again that I didn’t go for another physical for almost 10 years until just a few weeks ago. This time the doctor had me keep my underwear on except for when he examined me. When I asked him if I needed a prostate exam he sort of laughed and said I was still young and didn’t need to worry about that for a few more years. So I guess the “exam” I got at 18 was more for the doctor’s benefit.
