We all know CDC's 12 month data shows close rates of victimization for men and women compared to it's lifetime data. But I have found this pattern to be present in some more of these sexual violence surveys across countries.

France:

In a VIRAGE 2015 survey in France, an estimated 580,000 (2.90%) women and 197,000 (1.03%) men were victims of all forms of sexual assault in the previous 12 months.

England and Wales:

The Crime Survey for England and Wales (CSEW)%20and%201.2%25%20of%20men%20(275%2C000)%20aged%2016%20years%20and%20over%20experienced%20sexual%20assault%20(including%20attempts)%20in%20the%20last%20year) year ending March 2022 showed that an estimated 3.3% of women (798,000) and 1.2% of men (275,000) aged 16 years and over experienced sexual assault (including attempts) in the last year.

Netherlands:

A national population survey in Netherlands showed that almost 2% of women and almost 1% of men had experienced sexual violence in the past year.

These are just my observations, they do not confirm a pattern but it is indeed surprising that the 12 month data does not align with lifetime data. We need more research into this.
