My bf won't go down on me

Me (F15) and my bf (M16) have been together for 5 months, I go down on him almost every day, for the past 2-3 months. The thing is, he never goes down on me, he only did it twice and he doesn't finger me as often.

I've talked about it with him, and he says he doesn't like how it tastes or that it smells bad... I can understand and i've told him that if he doesn't want to do it i cant force him but for him to get in my place...

I've also explained to him that every vagina has a smell naturally and tbh it doesn't even smell that bad, it smells healthy...

He knows i'm a bit frustrated about the situation, rn i'm on my period but he told me he will be willing to do things more often..

Am i the only one with this 'problem'?
