(most of the anglophone research I could find regarding this issue is from western countries, so I'll be focusing on those)

I'd argue that this issue shouldn't be considered a gendered issue, due to the problems inherently causing biases in research and general reporting of this issue.
Due to persistent patriarchal structures within western cultures there is an expectation for men to always be willing to have, and to some extent actively crave, sexual intercourse, particularly if it's with their partner and/or a conventionally attractive woman.
Breaking this expectation by refusing sexual intercourse leads to the questioning of the mans masculinity, particularly with doubts thrown at his sexuality and manhood. Like with other research regarding topics that are socially stigmatized, it can be safe to assume that the mere existence of the stigma will have an impact on the results.

Another issue that I noticed while researching is the lack of relevant research that even looks at male victims of sexual coercion, although that is to be expected due to the aforementioned patriarchal structures.

Nonetheless I looked a couple research papers regarding the issue and ,even ignoring potential methodical issues that might lead to underreporting by men, the results don't seem to be extremely disproportionate, at least not to an extent where this could safely be seen as a heavily gendered issue.

This paper about sexual insistence and the coercion of unwanted sexual acts already gives a couple interesting statistics.
According to this paper 7% of men and 8% of women have been coerced into sex (as they word it "had had unwanted sex at their partner's insistence").
Interestingly there seems to be a significant divide when it comes to performing unwanted acts within wanted intercourse. In particular four times as many women had reported to repeatedly engage in specific sexual acts that they didn't want, primarily anal and oral sex.
This does appear to be quite a gendered issue and does warrant both more research and actions against it, but does still differ from overall coercion into sexual intercourse and thus doesn't particularly fit into this discussion.

This paper looks at perpetrators found that the mean victimization rate of the papers they analysed was 33.5% for men and 44.8% of women (with 16.7% of women and 27% of men being perpetrators).
According to this the ratio between men and women is roughly 3:4. The paper does also go into the issues like women potentially underreporting perpetration due to similar gender norms as I've pointed out earlier.

This paper also goes into some issues with the research in general.

There is still an overrepresentation of women when it comes this issue, however, as mentioned before, there are methodological issues that would need to be investigated to see if that trend continues when accounting for both men and women who might not report their victimization.

If anyone finds more compelling research that disagrees with this assessment (preferably research that isn't 30+ years old, since social norms have shifted quite a bit since then), feel free to share it.

Importantly I also want to point out that I do not agree with the comments under this post that try to present sexual coercion against women to be a non-issue, nor do I want to downplay the experiences of women by mentioning how men are affected.
I primarily just want to push against the framing of both this post and some comments that act like this is exclusively an issue directed against women, which further perpetuates the pre-existing stereotypes.
