Whats that tingling feeling that I feel when I look at pictures of my crush ?

It's believed that you're becoming link, there are nerves located there and it sends signals to your brain. I get that same feeling when I see my crush (pictured) in the film, Saturday Night Fever. When you become aroused, there's a small sensitive nipple-like shaped part called clitoris that's located above your urethra that fills with blood (as the same with the penis in men) and makes you become sexually aroused.
