Omg i'm gay

Well, I was doing some work in this building (I am a trades man) and this man asked if I could help him. He was instaling the electrics I'm this dark room.

Anyway I was standing up the ladder and he went up the other side, and i could feel his thing touching my thing and it turned me on. I stayed there and got an erection. When he was on his way down he touched it and giggled then pulled it out and done some very naughty things with it.

Is this normal?
