There's nothing physically being stimulated on my body when I'm getting assfucked, but there aren't any in my mouth when I'm going down on a guy, or in my hand when I'm jerking him off or between my breasts when he's titty-fucking me. But those can all be sexy. And like anal, they can all be unsexy.
Anal is maybe a little more demanding than some other things guys like you to do (handjobs aren't hard, maybe tiring!) but for certain men they are a big deal and I like to please and doing slutty/"bad" things that make the guy deliriously turned on can be very very sexy. One of the worst times--very painful and very long--also made the guy cum harder than any other man I've ever seen and he treated me like a goddess for weeks. It worked out in the end.
