I love to punch myself in my intestines and hear them growl at me in response.
Why do you love to punch your intestines?
I find it really erotically satisfying.
It's perfectly fine to have your own sexual quirks since everyone has them. However, you should be very careful about punching yourself. You can potentially do a lot of permanent damage if you are regularly punching your intestines.
Wait why?
Your insides are delicate and causing trauma to them can cause them to fail. Your sexual fetish can lead to you dying.
