Why he won’t let me give him head ?!

So my boyfriend & I have been dating almost almost a year , our sex life is great . Butttt he won’t ever let me suck him off 😂😩 he said he isn’t comfortable with that yet . Do you ladies really think that’s it or something else is up ?!

He doesn’t go down on me either , we just do other stiff and of course have sex lol . I need advice ! I feel so insecure that he doesnt let me , it makes me think things . HELP‼️😭
