any portrait of saint sebastian would look very nice, especially if you have other works of religious iconography in your home (although, i’m biased because i am into twinks). and if you don’t mind dominant women in your guro art, a print of caravaggio’s judith beheading holofernes might be up your alley. i’d also recommend looking around for classically-styled japanese eroguro prints. not too many artists specifically come to mind (since most of the ones i know of either primarily depict men, are very sexual, or both), but there’s definitely nicer stuff in that style too.

while not as “classy,” posters for old horror and/or exploitation films might also capture that same vibe. you can genuinely buy compilation books of those sorts of posters on amazon, kek.
