This question just came to mind thinking about having sex with a new woman recently. Just to note, I think anal sex is kinda boring, in so far as it essentially feels like vaginal but with more hassle, but it is fine on occasion for the perceived "dirtiness" of it. In the past five or six years, with new girlfriends, while having vaginal sex in doggy style, without asking I like to start fingering their ass, to the point it's come to be a natural thing for me. This has been met with two responses: 1. They say they like it afterwards, or during will say something dirty like "finger my ass harder" or mention it feels good. 2. They don't say anything. Maybe they like it, maybe they don't, but no mention of it during / after sex. This last woman I've been in a relationship with has never mentioned me doing it or alluded to it, but she always climaxes in doggy while rubbing her clitoris and me playing with her ass. When I was in my early 20's I did have a girlfriend who was steadfastly no butt play. She would freak at literally accidental touch of it. I'm in my 30's now, and not once after that girl have I encountered a woman who dislikes it enough to say stop. The question being, do you do this, and how do you find the reaction? Do you ever get any negative reaction from it?
