Is it okay for my bf to eat(kiss, lick etc) my *****? (my private part)?

while me and my bf were making out.. he starting finguring me... and then before i even know it hes eating my Private (my *****) part.. like kissing it and licking it and sutff.. I didnt like when he did that.. but it was actuly fun.. But i thought it was discusting that he did that. He said its okay.. its normal and when he does that it turns him on.
