I messed up BIG!! need help!

So my girlfriend and I were at my storage unit and we were making out, things escalated quick.. soon I took out my condom and my dick was soft.. I had a smoking hot girl and I couldn't rise to the occasion! W.T.F! Idk if it was the cold, or the atmosphere, or idk... she was soaking wet! And me, the dumbass could not fuck her! I'm going to the doctors tomorrow.. there's no way this is happening right now! I can fuck hookers, but not my girlfriend!? Fuuuck! I'm so mad!
