partner that's not really sexually into anything but the act of sex itself.

So I love my partner very much and we enjoy having sex together. However he doesn't really have any preferences or things that turn him on. Does anyone else have a similar partner or are like this themselves? He says just the act of putting his penis inside me or me pleasuring him is enough. What I mean by preferences or turn ons I guess Im referring to certain behaviors or fetishes if that makes sense. Like I personally enjoy being talked dirty in bed or being spanked, ect. But my partner doesn't really have anything that turns him on or gets him hornier he just is turned on by just having sex without any extra things. Anyways this sometimes makes me feel like I'm not doing good enough because I want to be able please him and give him his fantasies and make things special for him and also have him do the same for me but I feel like I am disappointing cause there's nothing special I can do to really make him feel special if that makes sense.. Does anyone else struggle with this?
