I Love Getting Tattoos Despite The Fact That I Black

I love getting tattoos despite the fact that i black out and go into seizures while they are still doing the tattoo. It does this every time, and i can usually start noticing when it's about to happen again. Do you have any logical explanation as to why this happens to me? I don't have epilepsy and would love to know how i can prevent or slow down these seizures before they begin tattooing.
