Husband loves to eat me out !

so my husband says he loves to eat me out but I get really nervous because of the fact that I think I taste funny ... but he says he love to eat me out I have never really told him why I don't let him eat me out as much as he wants to but I have noticed that when I deny him he gets upset .

I give him head everyday because I love pleasing him after a long day the sex is great with him as well but I can't seem to come around to the eating out part .....will I ever stop feeling this way ?
