I'm older than the men in this study, but I want to share my anecdotal experience as a contrast to the attitude of many in the comments, which I think are a superficial analysis of the situation. (This is assuming that the results are valid despite the small sample size. I don't really know how to assess that.)
I can really relate to these feelings when I was a younger man. I think the article nearly separates fear of being accused (self-preservation) with fear of moral harm (care for one's sexual partner). Because we live in a patriarchal society, men get the messages that women are false accusers or, equally harmful, that bad sex counts as rape according to "modern culture" or something.
Because I had people in my life willing to tolerate my younger self and teach me feminism, I know that false reports are virtually non-existent, that I shouldn't be so fucking neurotic about sex because I always care about my partner and consent in or out of a sexual context, that small mistakes don't make me a deviant monster, etc. But when I was 20? I heard the manosphere incel bullshit voices and the feminist voices, and I didn't know what to believe - I was young and naive and sexually frustrated. Thank God I made it through that without falling to red or black pill culture.
But we as feminists need better PR that educates just as much as it (justifiably) shames.
As leftists we generally think that society-wide problems have society-wide causes and solutions. We need to reach young men instead of just rolling our eyes or calling them people who just hate their sexual partners.
