You asked if feeling something on a self-DRE was normal, and I'll just have to say that nothing to do with a self-administered DRE could be normal. Unless you are a medical professional, you wouldn't know what/where to "look", and if you are a professional, you'll choose to trust things of the like to someone who knows better than you.
You most likely found the beginnings of a 'rhoid.
Anyway, You can go to your profile and use the 'signature' area to put less than 400 characters of description of your journey. Look at other sigs to see what sort of abbreviations are normally used.
