1.People look at you like you're crazy when you talk about toilet bowl water levels.
2. Casual conversation about what type of underwear you use can quirk a brow. "No, I don't like boxer briefs, I like boxers."
3. The either very awkward, or not awkward at all, part about buying Magnum condoms, because they shoot off like slingshots in holes, from the probably-17-year-old-female grocery store clerk at 11 PM.
4. In general, just trying to get anyone to believe that you've got a huge cock because every other guy on the planet lies and there should be a specific jail for these people and we should be able to throw rotten tomatoes at them. Thank God for smart phones.
