I’ve got a hemorrhoid and it’s fine, just be careful, especially at first. Use pscylium husk (it’s that orange flavored powdered fiber supplement). It’ll help with anal, but more than anything it’ll help minimize the amount you need to wipe, which results in less irritation of the hemorrhoids. Bidets also help, but not with the anal.

Use lots of lube, something small at first (a pinky finger is great) and go slow, once it’s comfortable you can slowly move up in size.

This also really depends on how painful yours is. For me it’s usually fine, but occasionally it causes immense pain, which did really put a damper on anal (as did getting bottom surgery). But by being careful and not rushing I’m able to avoid the pain.
