Sex with College Professor

So I have a hugeeeee crush on my public speaking professor and I think he might like me a bit too. At first it was just nice to have eye candy in class but now every time I see him I get the urge to just jump him right then and there. I'm 20 and he's 38. I really wanna have sex with him but I'm a virgin and I have no idea how to seduce a man. Any ideas?
