Germs

Things i won't do:
eat pussy or suck dick

so recently i think i have a germ problem, whenever i do something the first thing that comes to mind is "how many germs are on this?" So it's difficult trying to determine my sexuality. Because if i don't eat pussy am i not gay enough to be considered bi? But i also won't suck dick, so am i not straight enough to be straight? My limits when it comes to sex are VERY limited, i don't want to put ANYONES genitals in my mouth. I'm not eating ass.
