Have you ever been insanely attracted to a man. How did you manage it? Or have I lost my mind?

Basically the title. There is this guy, I am so freaking attracted to him I can't function like a normal human being when I think of him. I feel like a bag of hormones around him. What's wrong with me? How can I still feel this way in my 30s? I've neve felt this way with any man before. What is wrong with me
