hello im 18. and i have noticed my erection cannot pass a certain angle. I watch in porn and i see that peoples erection go at a much larger angle when they are erect. they can go up to 120 degrees sometimes, my erection in my penis can barely reach 90 degrees. if i try to push it anymore it will hurt! i have no symptoms of std's or sti's my penis is curved alittle bit up. for the record 0 degrees would be the penis laying on my stomach 90 degrees would be the penis pointing upward and 180 degrees would have the penis pointing to my feet (just saying to make it easier to understand). when i push it or try to push it beyond 90 it hurts around the base of my penis. i just want to know is this natural? will it go away over time? how can i fix it? because i want to do some sexual positions with my partner that have my penis go at a much greater angle but im afriad of hurting it in the process. note my penis curves only slightly upward it doesnt match the pictures of plaque forming in the penis. thank you.
