I was on the dart the other day standing as the train was packed, when this beautiful girl got on.

It gave me a massive erection, and I was embarrassed as those who were sitting down were looking straight at it.

I was mortified.

What should I do? as I would like to chat this girl up if I see her again, and apologise for my massive uncontrollable erection, which I presume is pure love.

Please Help.
