Hi

I am a 21 year old guy.

I have recently been experiencing a lot of erections even when I am not supposed to get them. For example: at work, during a meeting or a presentation, while socialising in public etc

At times it is embarrasing while it is distracting in other times.
if im at home it is no problem because i can jack off but if im at work or in public it is a problem.

is something wrong with me? How can i reduce this as it is interrupting my day to day life.

Thank in advance for your help
