Anal? We’ve only fucked twice

So basically we’re just casually having sex and taking “precautions” but the second time we had sex he straight up asked if we could do anal and of course I said no but in all honesty I like anal I’m just nervous to do it with him because let’s be honest we all know anal has a slight odor and I only ever did it with my ex who I was with for four years! So we were sooo comfortable with each other and it was never weird. I mean this guy is super chill and I think I’m just nervous because he’s so sexy 😂 lmao sounds dumb but I don’t know I just need advice.
