Wondering if i'm wiping too aggressively when i pass stool. i like to make sure i clean out my anus well. but i think i might be wiping too deep inside me. can you push too far inside and irritate the rectum? i'm noticing faint blood marks on the tp?

Your goal should be to eliminate any leftover poop that would stain your clothing. Yes you can push/rub too hard and abrade the tissue. Bright red blood represents bleeding at the outlet from a fissure or abrasion. The anus is designed to let stuff come out, not have anything put in.

You can reduce the damage to your anus by using moist towelettes. Wetting the toilet paper would help too. You may consider installing a "bidet" on your toilet, like a Toto Washlette. The washlette will ensure cleaning without trauma to the anus.
