It can vary yes.
There were times when I couldn’t wait to get home from work to fuck myself. Or when I had a girlfriend, to get home and make it clear that my bottom needed her attention. Other times for various reasons my ass would go untouched by me or by her, maybe work stress or digestive issues or personal problems that took all our focus away from our bedroom life.
Sometimes the focus would be on my girlfriend’s (or friend with benefits) ass, for days at a time when I just could not get enough of her, seeing her undress, caressing her bottom, spreading her open and just looking at her anus, kissing and licking, fingering, fucking, for what seemed like hours.
What always surprised me was these women’s willingness. Even when I was wanting more, they never said No or Enough. Yes a few women I dated had anal desires that matched mine, but others were very shy, a few had never had their anal area explored or had never touched (or even seen) another person’s anus, could not even say words like ‘anus’ or ‘asshole’ out loud and never initiated our anal play, but were quite passionately into the many naughty things being done to their bottoms. And would act quite shameless, even aggressive, when turning their attention to my backside. Lucky for me.
It is definitely an obsession requiring frequent attention.
