I don’t like kissing

Me and my boyfriend have been dating for almost 3 months atp. We are both newer to relationships and wanted to take it slower, so we kinda more recently just started kissing. Which I like kissing it’s nice but I REALLY do not enjoy kissing with tongue. I don’t know if we are like doing it wrong or something but it really just grosses me out so much. I feel bad because I think he likes it but I really don’t. I don’t know if I should continue doing it and hope that eventually I will like it or if I should tell him that I don’t like it. Like I said, we are both newer to relationships so I’ve never kissed anyone else with tongue before. Sorry this is kinda a weird topic to talk about but I genuinely don’t know what to do
