Guys who like rim jobs....

My husband likes rim jobs (his butt licked) and before I met him I honestly thought that was sort of weird but doing it to my husband is a huge turn on for me. I know some women are going to judge. It's okay. I'm just wondering if any of your husbands/boyfriends like that as well? And what are your thoughts on that. 
Also, what position is he in while you do that? Haha. I always want mine to try doggy style while I do it to him but he feels weird. Lol
