I'm 42. It happens more often than not these days. But I still recognize the internal signs.
I just figure by now, my dick can tell if something's going to result from seeing this hot guy. I liken it to a dog who originally jumps off the couch and runs to the door every time the front door opens. Butas it gets older, it sort of says "Enh, I'll get up if there's a pizza involved."
