I get really turned on when I'm intimidated.. I don't know what do, when my teachers yell at me I get really turned on and whenever I fight someone I get turned on. Any advice?

It's normal, don't worry. Ignore those two :p. It's called being a masochist, also if your turned on by physical pain. Someone who gets turned on by hurting someone else is called a Sadist. Hense the phrase *clears throat* BDSM. Which means;

B- Bondage

D- Discipline

S- Sadist

M- Masochist
