Is he gay or straight ????

Ive been having on going sex wit this guy for almost 2 yrs now... and never did he once ate me out... I asked him if there was a problem wit my vagina and he said no he just doesn’t eat pussy... so what does that mean because I have never heard of a guy never wanting to eat me out until I met this one... help me out guys because I get check on a daily basic and I always wash myself before sex... so what is the problem here
