Is it weird for a teenage guy to want to stick it up his girl's a**?

So this guy I have been seeing and I did it for the first time together. Everything about him is perfect but I think he has an a**hole . Like he started me and then he started my a** too! And then while we were doing it he was asking me to stick it up my a** but I said no. Is it strange for a teenage guy to want this? He also told me on vc he wanted to lick my a**hole.
