When on a roller coaster and going up and down why do I get a tingling feeling in my penis?


The "tingling" is the beginning of an erection. The roller coaster gets your heart pounding (raising your blood pressure). You also get tense from the excitement. Tension and increased blood pressure leads to erections. Since nothing sexual is involved, it doesn't become a full erection, but you do feel the increased sensitivity.
