Need advice if my BF is serious

I met him on an OLD platform. We’re exclusive and have been texting for 3months now. He’s texting me everyday consistently and said he would visit me early this year. My concern is that whenever we video call the majority of it is turning sexual. If I don’t give what he wants the call will be cut short. We only had one or two video calls where we really talked. I’m not sure if I’m overthinking this.
