23% in 2018. It was about ~35% or so in 2022 IIRC.

And then you have to also factor in that men tend to lie a bit on these surveys.

Also factor in that it's only asking if they got laid in the past 1 year. Do it 6 months, and the figure shoots way up. IMHO, the time gap should be no more than a month or so. That would define real incels. 1 year is way too much.
