Black pepper is spicy

I love spice, I always choose the spicy versions of food when I have the option, and even when something is a little too spicy I can usually just tough it out. But if there’s even a little bit of black pepper in my food I’ll be coughing and my tongue and throat will burn for at least a few minutes. Every time I’ve brought this up people have said I’m just being dramatic about it, but it’s seriously one of the spiciest things I’ve eaten.
