What can you do if you have a tiny penis and have problems going to the bathroom?

Sit Down?: It would need to be evaluated to see if your penis only appears small, is actually small but within normal range, or is a true micro penis. Sometimes reconstructive surgery can help some of the issues, but it can also create new problems. See your doctor, and if truely small or a micro penis, get a referral to a urologist that specializes in reconstructive surgery.
