I don't understand bidets

I recently got a bidet and I've been using it for about 2 weeks. Before I got it, I was under the impression that it would greatly reduce or eliminate the need for toilet paper (basically just need it to dry myself). However, my experience had not been that.

The bidet doesn't seem to do anything except make my ass crack wet. Instead of wiping with toilet paper, now I wipe with wet toilet paper. After reading a lot of experiences and everyone saying how the bidet changed their life, I feel like I'm missing something.
