Okay can someone with a Mac help me out here?

My Mac overheats like a lot. Right now it’s sitting on my desk (a flat surface obviously) and the bit directly above the keyboard is super hot, and I can hear the fan running pretty seriously. Is this normal? I’m pretty sure it’s been doing this since I first got it, but it makes me nervous!

it will be so fucking nice to have someone who finally understands the 100% real me, not just bits and pieces. the real me who has to always be kept hidden because a majority of people are so ignorant or hateful or who have some disrespectful comeback for what i explain to them.
