Wiping when you have a tampon in?

I don’t know if I’m wiping wrong but I‘ve had issues when wiping with a tampon in. I’m fairly new to tampons but I’m 24 and have no infections/Utis/anything that would suggest I’m wiping wrong.

When I’ve been for a wee previously while using a tampon, it hurts to wipe because the string get pushed against me. Just now I went to wipe after a number 2 and the sting got lost, when I found it it was covered in poo so how do you wipe with a tampon in without the string getting in the way.
