I'd say the effect of the last year made me more horny for kink.

As to why - I have to a greater degree been able to do sessions that leave marks, as the pandemic has eliminated most situations where carrying marks would be awkward (public showers, swimming pools etc). And with marks from a caning or whipping I walk around with a reminder of the last session that keep me horny and wishing for more.

(I have also been lucky enough to have a Mistress who stayed active during the period, and living a place with low infection rates and mild lock-down regimes)
