sunburnt while tanning?

i don’t even know where to put this but while tanning yesterday i stayed the whole 15 minutes, not just my usual 10. while tanning i spread my butt apart some, not thinking, trying to get the middle of my butt to tan, because it hadn’t been where it’s bigger. later last night my butt started itchy, so i came to the bathroom and wiped to make sure i hadn’t started bleeding and wasn’t dirty and that causing it. but it wasn’t. today i’ve itched some too. could i have accidentally burnt my butt yesterday, and that’s why it’s itchy? 😂 my actual butthole itches, but my butt did burn so?

SIDE NOTE! This won’t be anything sexual related and i’ve not changed body washes or anything so this is the only thing that i can think of 😂
