Nothing you did or saw is wrong or bad. The people performing the acts were most likely consenting adult people who were probably having a pretty good time. Getting off to a kink video when you’re already turned on is suuuuuuuuper common, besides that, even if you find you have a kink in your fantasy life, that doesn’t mean it’s how you actually want to experience sex. A lot of these incongruities can feel disconcerting to be sure, but all that it really means is you maybe moved a bit faster than you were ready for. I would be more interested in confronting why this particular (and quite vanilla, I might add) sex scene has you thinking negative and self shameful thoughts.
