This will also be covering sexual scenes that come with it. This needed a whole other topic of its own. I will list already covered points first.
USING TEETH IS NEVER OKAY DURING A BLOW JOB! IT IS NOT REMOTELY AROUSING UNLESS THEY'RE A MASOCHIST!
Semen stains. You can't just swipe it off your clothes (especially white ones) and call it good. It will dry and it will feel, smell, and look disgusting.
Depending on height difference, simply bending over is not enough. Think about whose legs are taller - someone is gonna have to squat. Also it hurts the back of your legs.
I should not have to mention this, but the anus does not self-lubricate or become wet. That is vaginas only.
You cannot physically deep throat a 9 inch cock. Put a ruler next to your face, and consider girth. Unless you can deep throat a large sausage, you cannot do that.
If the male is a teenager, believe it or not, they are extremely hormonal and in heated situations, generally don't take much to become erect.
Literally like two people on earth have a 12 inch penis. If you want to go large, go with 7-8.5. 9 is even pushing it!
ANAL IS EXTREMELY PAINFUL AND REQUIRES A LOT OF LUBE!! YOU PHYSICALLY CANNOT GLIDE IN DRY WITHOUT PREPARATION OR PAIN!
Spit is not a good lube at all, especially for anal. I recommend: Lotion, conditioner (if it's a shower), oils (ex. coconut), or actual lube. Use a lot of it!
When you have enough anal, your ass is gaping. Like right after it does not just close back up. It takes quite a bit of time to go back to normal
Going in dry will destroy an asshole and create a pink sock (Google it)
I completely understand for story purposes that you make a character gay, but generally characters aren't just naturally gay. Harry Potter has never proven to be gay. You may want to include some mental notes that he's realizing he likes a boy
