ok I did a show at my university about almost 2 weeks ago(I posted a topic on that a while ago to on the GBJF)
well the thing is that when the crowd responded so nicely to me and my band I got kind of ..well I guess you could say excited?...and my Penis erected and there was this noticeable bulge in my pants that the college photographer took (and focused on) and it appeared on the local uni newspaper.
Why does that happens? It's kind of embarrasing to say the least.

the headline read:
LOCAL ROCK BAND EXCITES THEMSELVES WITH BON JOVI COVERS.

It's true I did get excited ,it was kind of cool.but can anyone explain the reason this happens,because at every show I've done this has happened to me,and I don't know if this is a common thing or not.
