Nerve injury from sex?

Marlee
Alright so my boyfriend and I had sex yesterday morning (let me just say wow💥💥) and now an inch below my tailbone, (right in the crack basically 😂 ) hurts horribly bad. I've had the same pain in the same spot for about 2 months about 3 times total now. Ibuprofen helps to an extent but I'm just wondering if it's possible to damage your nerve in sex?
And no, it was regular sex
