Getting a hard on while extending

I’ve noticed in the last week or two since extending and doing PE again I get a hard on when the wind blows like a teenager. Just a thick veiny monster with a tiny head strapped into the end of the extender. Is this cause for worry? Will it deform my head? Not trying to sound paranoid just wondering if anyone has any information on if its alright and if not what is my best course of action. I do have pictures but this isn’t the picture forum.
