this is not going to hurt your prostate but it may not be considered normal for this to happen. you will need to see a urologist in order to be properly examined. there may be a minor surgical procedure that can fix this "hidden penis" issue.
when riding my bicycle my penis shrinks into my pelvis. it is very uncomfortable. is this dangerous to my prostate? . even when i stand up my penis feels really uncomfortable when riding hard or uphill. i am 26 male about 200 pounds and 5'9. i don't wear bicycle shorts.
