I too am quite surprised (and also not) at this. It's a given that the vast majority of people who are into our erotic fantasies would oftentimes be males, and therefore the subject matter would thus be heavily focused on females. It is also seen that many males enjoy playing females in order to help them fantasize of their arousals better.
It's not often finding good 'men in peril/doom' pictures and materials, which I high enjoy. Drowning in a river of sperm, for example, or facing impossible odds, interrogation and torture, or just good classic fantasy scenes showing a doomed male and his victorious opponent.
The few good works I could find are by Vittorio Carvelli, some nice works by Odinboy, and a few others. And yes, there seems to be too many Shota online as well. There will always be a bias effect where the vast majority of artworks and references would include females.
Having been roleplaying and exploring erotic peril and erotic doom since the year 2006, I have also felt that it is more exciting and arousing to explore with fellow males, especially those who are bisexual. I too am about a level three or four on the Kinsey Scale, and relate to myself as bi-curious, always enjoying exploring and roleplaying with whether males or females. Both can be very erotic and arousing!
If the anonymous thread starter or any others would be interested in exploring such together, I can be contacted on Discord via FantasyM#6196. I am always looking for others who enjoy similar and are interested to explore our fantasies together!
